I played Stephen F twice in the past couple months (most recently Labor Day weekend) and have to say that it is in excellent condition! I was extremely pleased with course especially for the $49 weekend rate.
However, RR is more of what I call a 'big boy' course. It's longer, more difficult, better facilities, and better players out there.
Just depends on what you're in the mood for. If you want a better experience with nicer clubhouse, range, bar hit up RR, but if you want to relax and take your time, sneak your own beer on, and don't mind some rough cart paths go with SFA.
Course condition wise I don't think they're that far off.
