To win several times your buy-in: Ring games
Play tired: Tournaments. You can always quit ring games, and the blinds stay small so there's simpler/less-severe stack considerations. IE, you can zone out and play ABC poker in rings and get away with it. But in tournaments increasing blinds increase the consequences of your bad plays.
To win the most $ possible in the long run: That depends on a lot of factors. Playing one tournament vs multi-tabling rings, I think most people will agree that a player with equal skills in both disciplines will make more multi-tabling ring games. But multi-rings vs multi-tabling tournaments, I don't know. Some people have a lot of success with tournaments (Sharkscope Tatta or BCM11 for example).
Of course, if you play what makes you happy, you win either way.
