I have both & can't honestly rate one over the other.
Both have their better options, both suck in certain areas.
To be honest, if I had loads of money I'd go for an expanded CD32...if little money, then just a standard CDTV with a few cheap mods.
If I wasn't into collecting I'd just move another miggy next to the TV & leave it at that.
Short story long...unless you are keen to collect more miggy models, willing to go mod-crazy or spend heaps of cash, then they are both perfectly useless if you already have an equivalent Amiga "computer".
