One other advantage of playing simultaneous turns as opposed to sequential, not mentioned so far, is with email notifications. All teams get email notifications of a new turn on Civstats with simultaneous turns. With sequential turns, it's only the first team that gets the email (since Civstats wasn't built with sequential turn games in mind). Of course we have the turn tracker thread here, but it's nice to have the Civstats email as well (at least speaking personally).
