What I really care about is how much time I'm interacting with the charge equipment. It sucks to be standing outside in the freezing cold waiting for your card to maybe get accepted only to find out that for some dumb reason the machine decides to decline it (forcing you to use an app which you likely don't have).
There's no reason all EV charging can't be a better experience than gas charging. There's already a data line established when you plug in (Both CCS and Chademo have data lines) so it should be beyond trivial for there to be a standard payment scheme (It should have existed from the start).
That depends completely on the charger. "Normal" DC charging stations are 50kW around here.
HVDC chargers go up to 350kW, but not many cars can utilise all of that, most cap out at 75-100kW.
If you plan things out well, you generally don't end up waiting too long for fast charging.
Using a Supercharger is even easier and more seamless than refueling with gas. Other EV chargers are generally much worse than gas. I hope they get there eventually, but right now it is a night and day difference in my experience.
