I prefer alliances. The problem with teams is you might get stuck with a nutball teammate and you can't do anything about it without breaking the game rules.

Alliances are better because you can make other alliances and then gank your old ally and remove him from the game making a better game for everyone else. It's especially effective if he doesn't suspect you are about to backstab him.

If team games had a rule where you could gank an underperforming teammate I'd be all for it.
