We put hundreds of hours in Stadia. Controller support was mostly OK, but not nearly as refined as DOS2. I don't remember ever feeling like they did a whole to fix the controller specific issues. Up until the last time we played, trying to target vertically was a huge PITA. It almost always resulted in using the trigger to snap back to another character, and at times, even prevented us from targeting an individual at all until we moved.
I'm pretty sure there were UI changes over the course of Sadia EA, but the vast majority of those were limited to PC. I remember reading all of those multiple page change logs only to find much of that didn't apply to us.
