Strategic and simultaneous are for 2 different things.
There is combat: strategic or tactical. I doubt that tactical is possible in PBEM, and at least would not be very advisable for obvious reasons   

  . 
Then movement: simultaneous or turn-based. I would always prefer simultaneous in a multi-player game, is much fairer to the players with higher player numbers. It takes some time to get used to it if you have played turn-based vs. AI up to now, but its not more difficult, just different.
So, unfortunately   

  , I have to agree to Fyron: it is kind of silly not to use PBW.
