The Craftsman Pros are really nice. They're a little shorter than normal, but they're nicely shaped -- it doesn't hurt to really lean on them. The finish is perfect and the fit is even better. They're by far my favorites.
The rest of my set was haphazardly assembled as I needed them or found them used. Besides the Craftsman Professionals, I've got Stahlwille, Wright, Williams, SK, Snap-On, Mac, Cornwell, Proto, Challenger, Armstrong and some cheap jumbo angle wrenches from NT.
The regular pattern (no. 13, I think?) Stahlwilles are short, but very thin -- great for big jam nuts and tight spaces, but harder to much torque on.
In truth, I think truck brands are overkill for wrenches bigger than about 1 1/4"; they're really nice, no doubt, but they're crazy expensive and I've never heard of anyone breaking even the cheapest of big wrenches. I can't really recommend the truck brands for that reason, though if you find them cheap, jump on them.
The Wrights, Williams, Protos, and SKs are all about equal. Proto/Challenger might make the best of that bunch The Armstrongs I have are old style extra-long pattern wrenches, with thin rectangular handles that approach being tubular. They're awesome if you have the room to swing them. They're my second favorites.
I've never used anything but the big angle wrenches from Northern Tool, but they're cheap as hell, strong, and very handy. The finish *****, and they could stand to have a little bit better fit, but I've stood on them before, so I can't complain. If you're not using them alot, I'd definitely recommend saving yourself a lot of money and going Chinese. Spend what you save on nicer tools that are more crucial.
