Both the Sega CD and CD32 were pretty bad in my opinion. But the CD32 always had the edge hardware wise. The CD32 can also be used as a full A1200 (if you wanted too?).
Anyway i love Sega systems but i thought the Sega CD's colour pallette was poor and the single speed CD drive was also nothing to shout about. (I can just about forgive SNK for the 1x CD drive in the Neo Geo CD because the games were great!
