I can't see how you can't have had the crown push in issue unless you either wear your watch far up your left wrist, you wear it on the right wrist or you've disabled the assistant long press. Even simple movements of my wrist will trigger the Google Assistant to fire up. It's a complete and utter design flaw that should have been picked up in testing.
It's also useless for Sport, although in fairness to the product, all Wear OS devices are useless for sport because Google Fit is far too simple. I used to own a pair of Sony B-Trainer earphones and the software on them was absolutely fantastic - I could set target pace, times, calories or heart rate zones. It would even change the music to a track with more tempo if I wasn't in a heart rate zone. All the running apps such as Runkeeper, Runstastic & Strava are just very basic tracking apps.
The screen is terrible as it's the poor quality P-OLED stuff that LG put into the Pixel 2 XL, although it doesn't look as grainy since Wear OS went with pure black backgrounds over grey.
