I use WSF (Winchester Super Field) with 165gr jacketed flat point and round nose bullets, in my Glock 22, 40 S&W. It's economical and gives me accurate target loads. Guys at my local shooting range were using it for our fun shoot competition and that is what they were using. It seems to work great in my Glock. I use Win 231 for my 9mm, 45CAP and 44 mag, which I believe works better in lower velocities. Although I've been reloading for 20 years, I still consider myself a novice in regards to all the different powders and their individual characteristics. Like everyone says, these days you use what's available.
