7800/2600 cores are largely done so they do make the most obvious sense. 2600 is the first thing most people associate with atari, and the older I get, the more I just love 7800 arcade ports, which somehow seem in an odd way more charming than more advanced 8-bit systems of the era. Somehow I've developed a special soft spot for rampage and galaga on 7800, specifically. I'd say my NT mini spends more of its time in 7800 land than any other core.
But If I had to pick one atari to live the rest of my life with, it'd have to be the A8/xegs. There's somewhere north of 20k games for the darn thing, so the library is huge. Quality-wise, a lot of the models don't even output svideo (in stock form), and it's really hard to go back to upscaled composite once you've tasted...better. But they're probably a hugely complex beasts if one goes down the rabbit holes of custom OSes and peripherals.
I'm waiting for any PRGE retro gaming surprises before I push the preorder button on the Mega SG, but I did already go for that controller.
