I just saw this clip and I want to make a few comments that are somewhat distinct from others commenting.
First let me say that I agree that the bottom clip is a better swing. Simply put it's more efficient. What do i mean by this? Simply put, it's quicker from initiation to contact. Then the question is why is this the case?
To put it into a basic context I have used to analyze elite level hitters: They do 2 things well:1] they create very good bat/body alignment from initiation to contact and;2] they rotate the trunk really well.
So, in using this basic functional framework, the second swing better exhibits this framework. Why?
The second swing shows a SLIGHTLY quicker hip rotation ,i.e., he rotates INTO foot plant [if you look closely the first swing shows a full foot plant BEFORE any actual hip rotation].
I would argue that this difference of hip rotation quickness is due to a more efficient stride process. Simply put, he has a shorter stride in the second clip.
Based on long experience [and certain physiological considerations], shortening the stride tends to facilitate a better [more efficient] stride to rotate process. [Ex. of a relatively short stride are Bonds and Manny Ramirez].
As regards the upper trunk: The first clip shows more counter-rotation of the spine/shoulder line. The first clip also shows a back arm/elbow alignment that is MUCH more elevated, relative to the second clip.
A note as regards the first clip back arm elevation [which gets above the head as he strides]. This is NOT scapula loading. Actual scapula loading is retraction of the scapula. In contrast what is seen here is shoulder abduction [along the frontal plane].
The differences are , functionally speaking, distinct and VERY different [this is twitter-- I will not try to further explain this].
In the second clip, the back arm elbow is MUCH lower [and I will add here that one COULD create very substantial scapula retraction in the posture/alignment].Now, how does this difference in back arm alignment matter here?
Well, if you look closely, you will see that the actual upper trunk rotation [the shoulder line] starts to unload SLIGHTLY quicker.
The relatively high elbow in the first clip HAS to lower and, simply put, relative to the second clip, it is taking a longer time for this to happen.
One could argue that in the first clip the shoulder rotation, in effect, is WAITING for the back arm to get into better alignment BEFORE the shoulder rotation can happen [as teacher I have seen this kind of situation happen MANY times].
Lastly this: A close look at the 2 swings--swings which approximate a pretty similar pitch location---the lead arm actually is aligned HIGHER to the chest from lag to contact. And the knob/hand path is slightly higher.
This might seem somewhat contradictory in that the hands/arms are quite a bit lower in the second clip.
BUT. I would argue that this is not contradictory. Why?
Well, because the second swing shows better bat/body alignment at initiation. Therefore, from that point forward, the CONNECTION of the arms/bat to the rotational plane of the shoulders was better!

Paul Nyman recently cited this as regards how many typically tend to interpret/analyze information:
You should read all of it. But I'll cite a few excerpts.
"The information we choose through our attention mechanism doesn’t always have to be the most valid or relevant. We rather try to pay attention only to the things that confirm our beliefs or opinions."
...." we look for environments that reinforce our beliefs. Since everyone around us thinks the same way we do, we believe our opinion is the one that’s right."

Prior to my foray into baseball/softball instruction, I had the great experience of working with James Cooper [well known as Adrian Peterson's trainer]. The athletes working with him were very good. Damn good actually. Many were track guys and football players.
In working very closely with these high caliber physical athletes, I began to notice something about those who really were the most most explosive, i.e., they could start ---and stop--VERY quickly [as in change direction very quickly],they could jump higher---and quicker,etc.
In being able to closely observe these types, what seemed somewhat puzzling and seemingly contradictory was this:

I recently had an experience with trying to convince a mom that her 15yr old son needs to work with me that I think unfortunately is symbolic of at least part of the cultural zeitgeist that we are living in. Here's the context:
I had talked to this mom about her son a couple of times at the gym about my background and teaching experience. Now I hasten to add that in these situations I am very sympathetic to parents in their pursuits to find good instruction.
My basic premise is along the lines of: "Why the hell should you trust me as someone who is REALLY knowledgeable and could REALLY help your son/daughter? Why would you NOT think that I am simply one of MANY who claims to be really good?"

In the first 40 seconds , Paul explains his ideas about the role of a coach. Essentially it is that of guiding the trial/error process and minimizing the degree of error, eg., practicing irrelevant things, not really understanding flaws and how to effectively correct them, etc.
I agree with this and I'll cite a particular ex. which is representative of much of my long experience as a teacher working with players.
Yrs. ago I was working with a 14 yr. old softball player. Pretty athletic, very focused, and very serious about wanting to develop.

My good friend[ and VERY smart!!] Rick Collins argued that the guy on the right was throwing harder.

To which Paul said: "The player on the right understands how to transfer/increase rotational momentum developed by the upper body to the arm using shoulder horizontal adduction."
Now [of course] Paul knows the answer ---because he did the simulations!
But. For outside observers the question is: How can one "see" ....correctly?
He cites ---as THE determining factor as regards the difference in velocity ---"horizontal adduction" ie., the back scapula continuing to "slide" along the ribcage [I refer to this via the more proximal articulation [scapula PROTRACTION].

"We truly live in a "one tweet" world of "information attention"..."

I completely agree with this. And this is precisely why I do not write any more than I do on twitter.
There have been numerous times that I have been prompted to write something about "how the body works" in the context of throwing/swinging dynamics; but nixed the effort on the grounds that it would necessarily entail some depth/precision of thought.
A kind of depth and precision that honestly I rarely see on twitter in the domain of throwing/swinging [or in other domain for the most part].
