Never owned a widow...never shot a widow till Friday a week ago. Been shooting a PCH demo for a week. 56" - 58#@28. But I don't have a comparison to any other widow since I've never shot one before. So sorry I can't give you any 'head to head' widow comparisons.
The PCH shot great from my very 1st arrow on the nock point that they installed, dead in the hand, not loud at all to me with the stock spider silencers but I could get it quieter with BowHush n Hush Puppies. I've never liked big heavy risered bows, and this one isn't heavy and doesn't seem that big to me. I like the stock grip as well.
And, the grip is not so close to the shelf that if you wear a heavy glove in the cold, the glove wont rise up into the arrow shaft. Some grips are so close to the shelf on some bows I can't shoot them in the dead of winter as the glove I wears humps up and contacts the arrow.
I didn't chrono it so I can't comment on speed, but it sure aint no dog. I can tell its a tad slower than the 64# bow that I have been shooting lately....but it is 6#s lighter. I'm sure if this bow was 64#s I doubt I'd be able to tell the difference in the speed of those two without a chrono.
I've been shooting it out to 60 yards and the most impresive thing to me so far is that the windage is TIGHT.
I can't find any idiosyncrasies at all.
