The interiors and exteriors were actually bad. The infotainment system was buggy and cheap, but it was feature rich and fast. If it wasn't Tesla, people would hate it for not having buttons.
The reliability is notoriously bad too.
I don't see any genuine argument for "Best", they might have the hardest, lowest paid workers, or the only car you can natively play a 30 year old video game, but when comparing Tesla to Nissan or GM EVs, I don't see why you'd get a Tesla.
It's more expensive and you get less.
