I think the personality is not an issue here. Laziness, low-energy or whatnot is only due to the environment we currently live in, those are not our true self. But If we could marry one of mane 6 and live in ponyville, where are more tolerant and friendly, less judgmental, less suppressed, I think we could be as energetic as Pinkie if we wanted to....
So yes, I would get alone with any of mane 6 just fine. As for marriage, my preference are Twilight, Rarity and Pinkie.
