Well, I'll chime in since I have most of the knives being discussed.
The Beckers have an excellent steel, but for me, I haven't found them to be good choppers. The CU/7 is a great knive, but not designed to be a chopper. The BK9 is better, but the edge is just thin enough that in wood it binds all the time. For other vegetation, however, it is terrific. They both have wonderful steel that takes and keeps a great edge. I use them for other things.
As for the CS Recon Scout and the Camp Tramp, for me it's a draw. The Camp Tramp seems to hold it's edge a little longer, but the handle is a little thin for me for hard chopping. The Recon Scout has superb balance for chopping, and also has great steel.
If I were looking at JUST chopping for a 7 inch knife, I'd go with the CS Recon Scout. For all around use, including chopping, I'd probably go with the Camp Tramp, although the line between it and the RS is very thin indeed.
For hiking, it's hard to beat the Beckers. Fantastic steel, light weight, and chopping (or batoning) in a pinch.
They're all 4 good knives. Pick one, learn it, get comfortable with it, and you won't have made a mistake.
