they use gotoh on the suhr guitars... need I say more? they also make a lot of the fender orig equip parts.
Haven't tried the callaham, but I'm certain it is made out of superior metal... I'm sure it's nice. The babicz stuff - have a full contact bridge. It is extremely nice and def a step up in terms of design, quality... does that translate to better tone - doubtful. Better tuning stability - def.
Still, if I was doing a vintage strat style (srv) I'd go goth. They have some good upgrades (the elongated post holes) and are (for my money) the most innovative company making guitar hardware. Support them for no other reason than to encourage continual research. locking studs, heigh adjustable tom, auto adjusting string posts, heigh adjustable string posts, side adjust truss rods... I could go on. On top of that their stuff is top notch quality and very competitively priced.
