These are all quite a bit cheaper to lease than both a Model Y SR, and a lot cheaper than a Y LR. Does having a much bigger battery make up for having to use non-tesla infrastructure?
Most of the cars listed with bigger batteries are shaped like a brick in comparison with the Model 3/Y, they need the bigger battery to get the same range as the Tesla.
For all its flaws and annoyances I honestly don't think I could do a non Tesla EV, the supercharger network is just that good.
The amount of apps and accounts I have for other public chargers is getting insane, imagine every single petrol station brand required you to have their specific app and sign up for an account with them to fill up with petrol and thats pretty much what its like on non Tesla chargers.
Some networks are starting to have plug and charge so at least once all setup it'll work like a supercharger - i.e. plug it in and let the car sort the billing.
In a year of ownership I can count on one hand the amount of issues I've had with superchargers whereas I've lost count how many times I've turned up to another charger and not been able to charge for whatever reason (no signal to get the app to connect, charger completely dead, charger not actually charging faster than AC speeds etc).
Don't undersell the charging network for a Tesla.
Of course if you stay near any of the new fancy electric charging hubs things might be better, lots of the issues with public chargers is down to the age rubbish locations of them.
If I had to, out of the ones you've tried out I'd go for the Skoda simply because it looks half decent, it hasn't went full touch senstive controls like the Volkswagen version and you get the Skoda simply clever stuff.
