The topic was "best EV car now" and not "best selling EV car" nor "best EV car few years back". They used to be the best EV car and Musk used to have huge charizma for many people. They were selling dream too. All of that sells, but is not "how good the car is" metric.
Tesla also used to have reputation of being well build cars few years back. I don't know whether their quality went down due to mass production or whether it was just not known about them.
They are not obvious winner among EV cars currently. They were first to do actual high end EV car and that vision changed the market back then.
