I think I would default to fire because during the main game all you need to know is water, switch out. Even then alot of fire starters have good level up movesets to handle all enemies.
But I'm starting to get back into pokemon. I haven't played much of these but I think I would like to play more of POISON, and PSYCHIC (or pokemon that have movesets that deal with putting enemies to sleep and doing sleep type damage spells) I know Darkrai has some like that.
