I have the 2CD Legacy Edition and the MFSL hybrid SACD of Kind of Blue, but never compared them, so I can't comment. Others did and preferred the MFSL because it sounded warmer.
"Hybrid" means that the disc has both a CD-layer and an SACD-layer, so yes, a hybrid SACD can be played on most regular CD-players, though in my experience some older players, from the 1990s for example, occasionally do have problems, which modern CD-players usually don't have. I have a 3-year-old Naim CD5 XS CD-player and never had a problem.
