The way damage calculations work, damage is reduced by Def/3. This means that +200 Atk makes way more difference than +200/3 Def (=67 less damage taken).

However, is it worth waiting until you get another type then evolving them from 2* up to 7*? Probably not. I would use what you have now if that is the case.
