It may not make a difference to you, but it does to me. The longer lock bars (rear release) tend to be easier to disengage. Whether that is good or bad is a matter of personal opinion. The blade "kick" that rests against the lock bar also hits on the blade pivot side of the lock bar pivot, meaning the blade can be pushed in when the knife is closed, potentially letting the blade edge strike againt the steel interior of the knife. In this picture the arrow points to where the kick hits the lock bar.
The tip of the blade will hit the inside of the blade well hard enough to dull it if the the blade is allowed to snap shut.
In this picture the arrow again shows where the kick hits the lock bar.
The blade cannot be squeezed in, and the edge will not strike the blade well.
Edited to do what I was trying to do in the first place.
