While I agree AT&T has gotten "better" I actually use a dual SIM setup with AT&T/T-Mobile.
AT&T a few years ago i'd not touch with a 10ft pole, BUT since FirstNet they've gotten **** mostly together, but I still travel many places where it's a second rate network in the city, and rurally I still have far too many areas it drops to HSPA even compared to T-Mobile now.
AT&T has promise, but they as well sat on thier *** too long and are just playing catch up now... as that's why "5Ge" became a thing - they were far too late to the party for any meaningful LTE upgrades and had to brand it as something else instead of admitting they were a few years behind Verizon and AT&T.
I do not hold much confidence in AT&T until this is all said and done, that company is like a titanic trying to make a u-turn on a dime, and it'll be at least 5-6yrs before they have a "meaningful" answer to Verizon and T-Mobile for real 5G,
Also in my line of work traveling all over... I rarely see anyone with anything but an iPhone on AT&T and they're usually a few year old versions at that. I have met maybe 5-10 people with a 5G phone on AT&T as the others with an iPhone 8 and above already think they have 5G thanks to the "5Ge" BS, so having less congested 5G at a ⅓ packed super bowl stadium is of no surprise

Verizon and T-Mobile have been pushing 5G phone upgrades quite a bit more aggressively than AT&T, whereas AT&T has iPhone Xs and Xr on "sale" for the last few months after the iPhone 12 promos went away.
