mysql8 has gis/spatial stuff built in now. may not quite be on par with postgis, but... i also don't have to futz with "doesn't come baked in". Dealt with someone who wrote a whole bunch of lat/lon/spatial stuff in client code because we're on postgres but ... he couldn't get postgis installed (then even if he could, figuring out how to convince the ops people to add a new 'thing' in production would have been a delay).

having stuff baked in is often a win.
