imho buck/strider folders are pretty darned good albeit heavy/thick folders, imho they are the top of the buck line, i dont care about the 110 personally i had several in the old days but carrying them without a pocket clip and no stud to open it doesnt work for me, i like the newer stuff myself, BM on the other hand makes many many diff models that all fit my needs perfectly (ie 630 skirmish, 806, 710, etc) so i would say due to having a larger selection of modern folders it would be BM #1 in this race, for folders, i cant even think of a buck that matches up well with the skirmish, for my needs anyway.
now fixed blades? another story, the 2 co's are almost polar opposites in this regard, BM with only a few FB while buck has many many models of them.
now in the '80s the 110 and the gerber FS11 were the thing, nothing compared to them, times change.
