Dreamcast was a very good console, with some minor setbacks, no 2nd stick and could’ve used a bit more disc space. The main thing that let it down was support, the short time it was on the market it did still bring in a bunch of really good titles, if only it had another 2-3 years and more longer story based games as well as the arcade games.

I would say because of the above the Mega Drive / Genesis is probably their best, simply because of the wide range of support and amount of quality games.
