The best class for solo games

[Particle_Man]

I would assume that solo leaders would have less to do, since they don't have anyone to inspire. The solo controller would be in big trouble, since he is relatively AC and hp poor, and at low levels doesn't have that many kewl powers.

A fey-pact warlock would be pretty survivable and could probably get out of any trouble he gets into.

For "can't kill it" solos, I would go for paladin. Tons of healing surges and no one else to spend them on. Oh, and best armor right out of the gate.

For 4e, I'd probably go with an infernal/star warlock, emphasizing Con and Int. You'll have decent AC, Fort, Ref, and hp. You can blast stuff from range, get out of trouble relatively easily, and get even tougher if you're in real trouble. I'd probably go with a dwarf so as not to waste precious actions healing.

Druid without a doubt in 3.x.

I'd second druid in 3.x, especially since wild shape + natural spell mean being a potent melee combatant and a full spellcaster at the same time.

Man... two rogues or a rogue+ranger group sounds like an awesome campaign. Keep to the shadows, develop some really stealthy things trying to keep the enemies at bay. Lots of stealing, diversions, traps... man.

Druid, Warlock/Dragon Fire Adept, Monk, Psion.

These would make good solo classes, and fun, too.

Depending on level, Artificer can actually be incredibly impressive.
