PPG Paints arena in Pittsburgh is probably my favorite. Not a bad seat in the arena, decent food selection, good fan interactions. Access to Penguins gear in several places, easy to get in and out. Parking wasn’t too bad. Dallas comes a close second for me, they have a pretty good setup.
Worst for me was probably Columbus though I wasn’t too impressed with Rogers Arena in Vancouver. Columbus just seemed to lack access to team gear and food options. Vancouver parking is terrible and the arena is just old, needs a refresh
Have also been to StLouis, Montreal, Vegas, Seattle and Miami. Would like to see a game in Amalie Arena in Tampa.
