There is no doubt Tesla has way more locations and number of charging stalls. I'm just trying to point out the EA is growing quick and starting off with 350kW chargers. They have accomplished a lot in 18 months. I'm also a bit surprised how slow Tesla has been to upgrade to V3 superchargers.
A couple of things to point out in regards to Tesla superchargers. When two cars are charging from a shared stall, the power gets cut dramatically. Not the case with EA. Also, my personal experience with charging my Model X is I rarely see the high charging speeds claimed by Tesla. Our's is a late 2018 so it doesn't have the Raven battery. But again, compared to our E-tron and Taycan, it's extremely slow. Also you mentioned Tesla's slowest charging rate is 120kW, but the problem is Tesla's ramp down so quickly that they are charging in the 50-80kW range once the get above 60-70% versus the E-tron for example charging at 150kW all the way to 80% and above 100kW to 90%. So there are times which older Teslas or the Model S and X can have a big impact on turnover. Kind of like a slower charging Bolt which takes about an hour to fully charge.
I've had great success with the EA chargers in Colorado. I understand EA has had issues rolling things out, but my personal experience has been great. Also no lines or waits to speak of. Now granted as more and more EV's by other brands get released this will become a big problem at EA.
When we bought our E-tron we planned on it being our "around town" EV and the Model X as our road trip EV. But based on our experience charging it's changed. We now tend to use the E-tron as our preferred road trip car.
