I did a comparo a while back.

I did NOT like the Milwaukee - the crank-down with a screwdriver is a good idea, but they deflect a lot when clamped.
The Pittsburgh had a nice release, but is just plain cheap. Work, but are pretty basic and light-duty. I wouldn't bet on how well the teeth will survive/etc. No crank-down help.
The vintage Peterson is nice, and probably the best bang for the buck if you can get them at flea market prices and not beat to ****. They don't have any provision for crank-down help IIRC.
The Bremen was pretty close to the Peterson pair in feel/quality/etc. Virtually zero deflection when clamped, pretty aggressive teeth. I liked the 1/4" square drive for the crank-assist. I'd put them at/above the box store brands (Crescent/etc.).
The Malco pair was a work of art - manifestly felt like a high quality tool that was vastly better than all the others. Unfortunately it cost vastly more than all the others. Fine if you're only getting a couple/few, brutal if you use a lot.
Bang for the buck new, the Bremen is pretty great. I did wind up buying a few pairs of Malco. I tidied up the vintage 7"/10" pairs I got, but they're not in great shape.
