Though the 2 years of free fast charging you get at Electrify America is a nice bonus on the Kia and Hyundai. For me supercharging is nice but this is my daily driver and will rarely if ever use a supercharger. The others do have some convenience as well. There are Kia dealers on every corner so I'm sure the service experience is much better. Even with those perks, 2 years free charging and a $7500 tax credit I still went with the Tesla .
I'm kinda the reverse as I compared the Ioniq 5 / EV6 to the Model Y as they are closer in size (Model 3 is noticeably smaller). I don't think the $14k difference was justified so getting the Ioniq 5 instead. I also think that if you live in a place like California, charging network becomes a smaller consideration.
