For my taste, RTwP ("real-time with pause") based, like in Planescape: Torment and Baldur's Gate, is best of two worlds.
While characters are always in action, game automatically, depending on how you set it, pauses when certain conditions are met (enemy spotted, enemy attacks, critical injury, spell cast, weapon ineffective...) or you can manually pause it at any time so you can give commands to all your characters at your own pace.
