For gaming, it's mostly not worth it. There were some games that will use it (Napalm, Quake and a few others) and a few games had RTG patches, but they are generally all "late" amiga games.
For general day to day use, it can be cool, if you find a cheap one. If you want a high resolution, 256+ colour workbench, it's generally the way to go (AGA can do 256 but it isn't fast)
