I think I'm qualified to answer this question!
I've owned ALL THREE that have been mentioned!
I currently still have the Camillus and the Leather Washer Handled Ontario. I traded the "rubber" handled Ontario for the leather Ontario.
I find the Camillus sharpens better and holds an edge somewhat nicer than the Ontario. Sorry I can't get more technical with my description than that...
The Camillus blade treatment MUST have something to do with what I'm trying to say. Refer to Rob's post on that!
As to the reason I traded the 'rubber' handle for the leather-
1) Solid pommel for pounding!
2) HANDGUARD!!! The rubber one doesn't have one and it was slippery when WET!
3)The rubber handle was SOFT especially on the pommel end and the finger guard where it projected from the tang.
So from an owner of all three, go with the Camillus!
Good luck!
