Actually, I prefer the EPA website,
www.fueleconomy.gov:

The 2021 Std Rng Plus Model 3 has:
- 4.2% greater range = (250 - 240) / 240 miles
- -6.0% lower cost to operate = (0.78 - 0.83) / 0.83 cost per 25 miles
Although the 2020 is more efficient and affordable than my 2019, the difference is not enough to cover the cost of upgrading. But as I mentioned, I want to test my $6k FSD. As for the five year warranty, there will be 1-2 years remaining in 2022-2023 which improves the trade-in value.
What surprised me:

The Time to Charge Battery:
- -10.5% faster = (9.5 - 8.5) / 9.5 hours at 240V
Of the spec changes, this is especially helpful for cross country driving. It means charging stops, especially maximum range, can save an hour. There aren't many maximum range segments in the SuperCharger network but it is nice to know they will be faster.
I fully understand that some buy a car as objet d'art but my cars work hard for a living. The non-EPA web sites don't bring money or a comparison of vehicle efficiency. You of course are welcome to pay whatever you wish. Personally, I'm cheap.

ps. These are four of the top five EVs. I omitted the "2020 Hyundai Ioniq Electric" whose performance is worse than the 2019 model. No need to embarrass the competition who are 'de-evolving' their product.
