I've had a Proformance1+ for a few years and I was quite happy
with it's sound until I got an UltraProteus. The UltraProteus
has the same piano samples that are in the Proformance, but they
now make use of the UP's filters etc and sound much more vibrant.
The Proformance still sounds OK, but it sounds very flat compared
to the UP piano sounds. Hitting a note harder just makes it
louder, not brighter like in the UP pianos (and others). It's 32
note polyphonic (16 stereo). It depends what you want to use it
for of course. I wouldn't use it for a solo piano piece, but
it'd probably be fine banging away in a mix where it isn't the
focus of the piece. Look around at the latest modules first
I'd say, the Proformance is a few years behind now.

I think this is a really subjective issue. By the way, I think you mean
the Roland P-55, not S-55. In any case, the best think to do is play
them for yourself. When you check out the P55, make sure to change
the settings to suit yourself. On the P55, you can adjust a lot of the
parameters of the sound, such as reverb, chorus, filter cutoff, keyboard
scaling, etc. Whereas the proformance is pretty much 'what you get is
what you get'. Don't forget to check out the other options too, namely
the Kurzweil piano module. You might want to check out a Quadrasynth
Plus Piano module as well (with the QS module, I don't think they have
the good piano built in to the module, you have to use their piano
plug-in card to get their best piano samples).
By the way, I went through this whole exercise, and for me, the Roland
was the best. Although the raw sample sample quality is not quite as
good, it wins on other points which are more important to me. Namely,
it seems to respond to velocity better than the others. I.e., the tonal
range is more responsive, from ppp to m to fff. At least, to my ears. But
I can see why a lot of people like the other ones, too. Oh, I also have a
Proformance, which I also like, but only in stereo. For playing live,
I use mono, and the P55 sounds better in mono. To me.
