I greatly prefer AD&D2 version. Aside of obvious flaws (telepathy being overpowered because it's cheap and there are no natural defenses) that could be patched rather easily, if at the cost of more mechanics (I’d modify contact cost by size, for one: then a telepath can nudge a Zaratan in a pinch, but it's far more tiresome than messing with Medium sized critters).
Both balance-wise and flavour-wise, the old implicit philosophy was mostly good. The difference between psionics and magic is like between doing things with your hand and a mechanism: trade-off between finesse and concentrated raw power. Thus on the one eyestalk, most protective spells, even high-level, are not absolute prohibitions, but merely contests. On the other eyestalk, no vulgar power effects comparable with fireball, and disintegration is quite expensive; also, everything is interactive, so psionic invisibility is to the target only.
Skill mechanics for this mostly “feels right”. Except excessive unreliability, but this applies to skills too. Which could be eliminated with one of the few good solutions in d20: “take 10 ” rule.
