Sadly I don't have any of those teams, but I think you wouldn't go far wrong with any of them. (that doesn't help you much).

Personally I think druids have it all, and would be the most flexible group should you change your mind about what you want to do months down the line.
It's the group I would roll if I could be bothered levelling anything else up.

Stealth - sneak attacks even if you are a caster, self healing, battle res, normal ressurection, Roots. If you are bored of being a caster regear and become melee
and I know you don't want a trinity group but you could change it in to one if someone puts a gun to your head.
