This is probably not "PC" to say, but having owned RAT5, RAT7 (1095 and D2), BK2, BK7, BK10, and more, I still prefer the edge geometry and edge holding of a Fallkniven S1 or A1.
I've used my RAT7, RAT5, and Beckers very hard and they are solid knives, but I can never get the handles to fit my hands very well no matter what I do. (I have large hands and yet the RATs feel like a 2x4 in my hand and even the Beckers feel large.)
My recommendation is to go to a cutlery store or gun/knife show and try them out. See how they feel in your hand, then make your decision.
That said, I just got another BK2 just in case they are discontinued forever and ever...
Regards,
Mike
