That all depends on your,
That all depends on your, your needs and preferences. The CX-90 is going to be more larger, more capable of hauling people and stuff, and is almost certainly going to be more feature rich/luxury oriented than the Rav 4 Prime. I would assume that if you drive it gently (accelerate like you’re not in a hurry and coast as often as you can, keep it to within a couple miles of the speed limit) you will likely be able to beat the EV range and get better MPGs while doing so, maybe 10-20% on a regular basis (or more). This is certainly the case for me and my Kia Sorento PHEV… I regularly get 37-41 miles per charge and my lifetime average fuel economy when running in hybrid mode is almost 37 MPG. But I drive it in a leisurely fashion and I plug it in every chance I get (went almost 1,500 miles on my last tank of gas and could have stretched it a few hundred more if I hadn’t wanted to be repaired for a possible improved weekend away). I say: ask yourself what matters to you in your next PHEV. Is it efficiency? Space/capability? Luxury/feature content? If it is efficiency, then yes, you might want to look at the Rav 4 Prime or another PHEV SUV that gets better efficiency than the Mazda (Kia, Hyundai, Mitsubishi). Best of luck to you!
