Given the choice between as Case tru-sharp, or a Buck, which would you prefer?
Buck easily. Even though both are 420HC, Bucks heat treat is better.
Recently I compared the performance of Case CV to Case Tru-Sharp,

When I tested them, I also ran the Buck 301.
I just left it out of that review because I did not want to muddy the water.
In Blade hardness, they ran like this:
CV______54
TS______55
301_____59.7
In manila rope cutting, they ran like this, least edge retention to best:
TS, CV, 301
Which is what you would expect with hardnesses running like that on similar steels. (Once I finish comparing the 301 to other steels, I'll likely write that up as well as a separate review.)
Now the fit of both the Case and Buck was good. The Case felt better finished as all the corners were gently rounded while the Buck felt a bit more angular. The Blade snap on both blades of the Case TS Trapper was very good. The blade snap on the 301 was good on two blades, less good on the middle, but still adequate.
If I wanted to give a knife to a non-knife user, I'd choose the Case because it feels and looks very classy.
For me or anyone who really USES their knife, I'd choose the 301.
