If we are throwing anecdotes out, most of what I have heard about Psionics from 3.5 and Pathfinder have generally been discussions of "I love my X character, they can heal better than the cleric and throw out [arbitrarily high number of dice] for damage every round and as long as a have [technobabble of abilities] up then the enemy can't even hit me."
Granted, that and the "my character is a [list of 6 different classes and prestige classes with a race that is half-template jargon]" are about the only 3.5 stories I ever hear beyond the bad stuff, so I can acknowledge that a small sample size is probably at fault.
