I had a 2018 X for, well, about 4 years. I've put about 8k miles on the refresh and wanted to share thoughts for anyone thinking about upgrading.

Range - Huge win. I went from 270 to 340 miles, and faster charging. Add it all up and charging stops are about half as long as they used to be on road trips, since you can stay under 60 percent easier. Great!

Interior quality - Good improvement. Nicer materials. Everything is just a touch better. Still a small step down compared to my Genesis GV80, but it's fighting in the right league now.

Speed - Noticeably faster, even without plaid. Teslas are very fun to drive, and the refresh is better.

Autopilot - Draw to slightly worse. I don't have the phantom braking issues I was expecting, and some parts work better, but there are a lot of small new bugs as well. Stop and go traffic, one of my biggest priorities, is worse as it slams on the brakes when someone 20 feet ahead slows down. I have to wonder if this is because they axed the radar. It ends up being slightly dangerous in city highway traffic jams.

Controls - Disappointingly a little worse. No stalks, the yoke looks cool but isn't as functional, I'm tired of the button turn signals, I honk when turning on autopilot once a week, etc. These are just unforced errors, and while none are as bad as I feared, they are absolutely a small step back from a normal car.

Audio - Neutral. Was hoping for something a bit better, but no biggie.

Rear seat screen - It exists. Not really sure why it's there, or why there's a powerful GPU. Please give me more range instead. Kids don't really watch it because it's strangely positioned.

Suspension - A bit better. Again, not bad, but not as good as the GV80.

360 surround view - how is this still not a feature?

7 seat vs 6 seat - 3 wide second row is great if you have 3 kids. 3rd row is worse, but if you can use it a lot less, 7 seats is the way to go. Plus you get extra cargo space most of the time.

Overall - Neutral to a bit better. I buy Teslas because they're the best car experience. I think that's still the case this year, but after seeing their trajectory and what others are doing (I'm looking at you Volvo EX90), I don't think they'll be the best next year. I'm surprised that 4 years of development and a refresh didn't really raise the bar. It's like a minor refresh. Awesome car, awesome superchargers, but it's odd there aren't more improvements or innovations on the horizon.
