LOL - Silly that I never thought to check out the forums at Arduino proper... Most questions are probably generally related to generic ESP32 discussions, but there also seems to be a fair number of M5Stack users as well ;-)
Each seems to have some different strengths - the Fire has more ports, the cool magnetic base and physical buttons that often work better than touchscreens. As such it's great for tinkering. But the Core 2 seems a bit more 'polished' for portable applications.
