The only option that seems applicable in this poll is lemon curry... We've had less than 10 psionic characters since I started playing (back in '94), but that's way more than some of the PHB classes (rangers, generic clerics (2e), bards, druids, most specialist wizards, monks, and barbarians; probably paladins, too).
Back in 2e we had a pretty high turnover rate of characters at low levels, as the game was pretty deadly back then. Or it seemed deadly... I'm not sure, we were younger and probably played it differently than we do today... Oddly enough, I was happy when we switched to 3e back in 2000, but now, looking back, 2e is the system I enjoyed most, and, after a decade of hiatus, I still remember a lot of 2e rules, where I've forgotten most of 3/3.5e era...
I remember a half-elf psionicist inspired by the Bene Gesserit from Dune, created under the revised 2e psionic rules in, IIRC, PO: Skills & Powers (with MTHAC0 and MAC). I've had the Complete Psionicist's Handbook, but I don't remember if I played any psionicists using those rules. In 3/3.5e, we've had at least two psions and at least one psychic warrior that I can remember.
The Skills & Powers version of the psionic rules is my personal favourite, to be honest. It was more streamlined than the Complete Psionicist's, and the I hated THAC0 (and MTHAC0) with the burning passion of ten thousand suns, but the system felt good. It was completely different from magic, but flavourfull, and complete.
The 3/3.5e version was different. Magic by a different name, and generally too much focused on crystals, and I thought psychic manifestations (was that what they were called? those sensory bursts people felt/saw when you manifested a power) were a bit too much (I was OK with the taste and smell ones, but lights and sounds felt weird).
I barely remember 4e (barely played it), and I don't remember any psionic characters.
EDIT: I forgot to mention, almost 95% of the D&D campaigns I've played in were set in the Forgotten Realms. I think we played a session or two in Dark Sun under 4e, but I'm not sure (that's about the entirety of my 4e experience).
