I would probably pick #1 or#3-
maybe with #4's handle, assuming we're talking about a knife whose primary focus is chopping.
The ones I really like aren't in the original post, though.
Those are some exceptionally well thought out knives for say a large all-arounder and dedicated chopper, respectively. I could go on and on about all the features I see them bringing together, and why the differences between them are well suited to the change in overall size and weight(ASSuming I'm judging the sizes well).
The big one looks like a great chopper, but the top one is just plain impressive from one end to the other.
I might actually carry the top knife in spite of it looking a bit large for me to want to tote around.
The ergos look great, and the knife looks like it would be quick in the hand for light brush while chopping well for its size. Love the swoop of the blade, how it combines with a relatively high tip that is dropped enough to penetrate well and still be very strong, that the sweet spot is probably going to be right behind the widest part of the blade to maximize chopping ability for its size, and that most of the edge is straight, but with a "negative included angle" that will make maximize its slicing ability.
Awesome, awesome knife.
Where does it balance...an inch in front of the scales, maybe?
Well, maybe I did go on and on
