I have the Bushman, its very sharp, check out the test at knifetests.com - pretty impressive for a cheap blade.
The GI Tanto will be tough as nails - probably as tough as a strider knife - Les Thompson is no dummy, he will kind of undercut Strider with that knife - all the more power to him.
I have a CS Oyabun in Carbon V - its hands down the sharpest big knife that I own.
I have nothing bad to say about Cold Steel knives, I just prefer to have a "relationship" with my knifemaker, instead of buying knives from a guy that farms out his production.
