Bullseye is probably the most universal powder for pistol cartridges with W-231 coming in a close second. I have used both in my S&W Model 52 with the 148 gr. Remington LHBWC - 2.7 gr. Bullseye or 3.2 gr. W-231 provide equal accuracy in my gun. WST and American Select are cleaner burning than either Bullseye or W-231 at the same velocity level.
