I hate CE 2. The gfx are way worse than in part one. The gameplay might be ok with 2 players, but sucks horribly in single player, etc...
I don't like CE AGA either though, I much prefer non-AGA version. The AGA version looks like a quick and cheap recoloring. The AGA palette is too colorful and not consistent in style.
But most importantly: the carefully hand-drawn anti-aliasing got totally messed up when they re-colored Chaos Engine for AGA.
Bottom line: CE non-aga forever!!!
