Consider a list of predicates for an object and the fact that there is a logical priority of considering them.
This is just an example, so please do not focus on the requirements themselves.

Left side contains a case statement without a case condition and the right side the same logic implemented with if/else.
Which one do you prefer and why?

Here is an alternative (right side) using guard clauses instead of if/else.

Somehow, for me, the case statement makes more sense when I take into consideration:
• the order in how the conditions are assessed
• it is a bit more open to add more statuses
• I somehow feel a bit uneasy after using 2 guard clauses (or early returns) in a method
But I like also the variant with guard clauses or the if/else.
