Go look in peoples cars and ask to sit in their seats. My size requires a larger seat, and I got lucky with the Sparco Evo2 FA (fat ass). That seat is very comfortable and supportive. Now, extra safety dictates the head halo, but it can be very restrictive in entry/egress. Simply for that reason I would not buy one because I could not get out of the seat in a reasonable amount of time (and NASA thinks you should be able to get out in 10 seconds or less) Trial fit and get the one that feels the best...you should be able to fall asleep on the grid, as I do on occasion.
