I'm assuming you're talking about the Case SBJ with CV blades, right? That is a tough call.
The Case is a little bigger, but slimmer & lighter (If that makes sense). However, the GEC's a little stouter & can be had with a Sheepsfoot/Wharncliffe blade (Usually with a small Clip blade instead of Pen blade, though).
I'm not sure the Case's F&F is better than the GEC's, either. I also think GEC's 1095 is better (In edge holding) than Case's CV steel & if it's available in GEC's 440C, I think theirs is better than Case's Tru-Sharp, too (Again, in edge holding).
I'd say get both. Life's too short to pick just one & they are different knives. I love the GEC Barlow in frontier bone.
