EGS Spectrum works with Cybergraphics too. I have EGS, Picasso 96 and Cybergraphics in separate system partitions on my A2500. EGS is amusing and retro. It is actually a completely different 24 bit GUI piggy backed on Intuition. There are only a handful of apps for it. It also gives you a 256 color Workbench. Picasso 96 and Cybergraphics give you a full 24 bit workbench. I personally prefer Cybergraphics but Picasso 96 is a bit faster.
If you ever felt like taking the time, I admit I'd be really curious to see a kind of side by side/quick comparison youtube vid of your setup
