I just cannot seem to get SSC's to fit me well, and I have tried quite a few. Mei Tais are also infinitely adjustable, where with an SSC, I am limited by the length of the buckle straps, which since I am small, usually were way to long. I could never get things tightened down enough. I also did not like that SSC's really structured waist band always pushed my pants down. Now I do like a padded waist MT, but I think it works for me since you tend to wear an MT waist in a different position than an SSC waist.
That being said, I am a wrapper at heart, and rarely use MT's anymore. DS is currently 30+ lbs, and will be 4 in March.
