I've always felt this way about PS3/360:
"The 360 now feels slow and clunky by comparison, and the framerates in many games are quite off-putting"
Which is why i started gaming more on PC as last gen went on.
PS4, and I assume XBO dont seem to have that same issues. Sure they are not blowing us away in the graphics department yet (as PS3/360 did), but everything else has been pretty darn good.
