Next campain.. which faction?

Hello friends!

I just completed a campaign (medium difficulty I think) with Massilia and in less than 200 turns completed the economic victory (also using the IA uses pop + coalitions)

Knowing that I would not like to play with Carthagine, or any other greek culture, which factions would you suggest me?

I was thinking to go in Britain (Iweriu or Iceni) or even play rome for the first time!

What would you suggest?

Thanks!
