Which MTG Commander deck should I play: fast Vivi burn or Terra combo?

I can stick with my Vivi Ornitier deck, which can win on turn 2 but usually wins on turn 4. The problem with this deck is it mostly ignores the opponents while pinging everyone to death for 40 damage. This pisses everyone off and they focus-fire me and try to eliminated me immediately. This has only been a problem vs other Vivi decks and one other deck though.

Or I can try to make a Terra, Magical Adept Deck based on Final Fantasy and Thassa's Oracle. Theoretically, this deck can also get lucky and win as early as turn 2, but i smore likely to need 5 or 6 turns to win. The advantage though is this deck won't' piss off my opponents very much, even though it is considered "EDH" which is the highest tier deck.

I want to try something new, because I've been playing the Vivi Ornitier deck for like a year now and I only play like once or twice per month.
