I have 3 PRS and 1 Suhr. The PRS's are all Core line (not SE, CE or S2) - Signature Limited, SC58 and Custom 22 (10 Top). The quality is fantastic. The Signature Limited and SC58 where both special limited editions so you expect them to be special and they really are. The Suhr is a Pro S1 one and it's also a great guitar. The Suhr came with the traditional style trem that wasn't very good at all, but that's what they used in 2007 when she was built. I sent it to Suhr to get the trem replaced with a Gotoh 510 that they install in newer ones and now it's a really, really good guitar.
In terms of quality, I would have to give a slight, slight edge to PRS, but there's really not a lot in between them. If I could only keep one it would be my PRS Signature Limited, followed by my other PRS's and the Suhr last. But that really only comes down to that I'm much more of a dual humbucker guitar guy and Strats have never really felt as home. I also never owned a Tele and it wouldn't suprise me if I end up with a Suhr Classic T at some point. And that to me is really what it comes down to. If you prefer Strats or Teles, Suhr is the obvious choice. If you prefer dual humbucker guitars, I would pick PRS any day.
