Interesting analysis. I previously owned a 2021 Toyota Prius Prime Limited, and before that a regular 2010 Prius (which I still own and it has 240K miles on it and going strong). Toyota makes an excellent automobile in my opinion, and I can definitely see the value in the RAV4 Prime, but it just doesn't have enough range in my opinion.
The reason I sold my new 2021 Prius Prime after just 2 months is because I found liked the EV drive so much I never wanted the regular gas engine (ICE) to kick in. The Prius was an amazing car otherwise, but only got 25 miles of EV driving per charge, and this was too little. If I could have gotten the Prime with a larger battery I would not be buying a Model Y.
Now the RAV4 Prime has a little more EV range (42 miles) but still not enough for me since my daily commute is 100 miles.
Seriously, there are so many great things about the Toyota that I will miss because they are just not available in the Tesla. It really just came down to the EV range for me. Once I started looking for either a hybrid with longer EV range or a BEV I came to realize that there are really only a few choices I would consider. The 2022 Chevy Bolt EUV of course, the VW ID.4, the Ford Mustang MachE, and the Hyundai. In my opinion the Tesla beats all of these and is not much more expensive, so I decided to go with the MY and just live with the missing features.
If you can live with 42 miles of EV range most days, I see nothing wrong with the RAV4 Prime. In a few years EVs will be better and cheaper. You could always switch then.
