The XEGS was just another recycling of the same 8-bit tech that goes back to the 400/800. I have one, and it's fine, but it's no different than the others, including the 5200.
It was I'll timed to be sure, but now as a classic console and with access to the 8 bit library its a real gem. Has the library size of the 5200, 7800, Jag and then some..
