It depends on the type of "feel" you want. If you like the long "throw" (the distance between rest/neutral to the switch activation) of the old western-style SF2 cabinets, go with IL Competition sticks. If you like the quicker, shorter throw of the Japanese style sticks, go with either Sanwa or Seimitsu. I personally like the quicker style sticks, especially for games that require dashing/parrying (ala tapping the stick) like SF3 does. I also find them quicker to maneuver and react throughout SHMUPS.
