But, again, that doesn't tell you how many chargers there are in each location. From experience I can tell you this is very important. And an area where Superchargers are currently vastly superior.
That is actual chargers and not just locations.
I agree that the Supercharger network is superior for speed and ease of use currently. I would say CCS is easier to find but more fragmented and often needing more effort.
I'm sure your experience will change for the better as the I-Pace has a far longer range than the Leaf.
Why did you not hold out for the Model 3? It seems the right car for you.
