Why not?
A bunch of reasons. The Rav has more power, will be better on gas, has a conventional auto, will likely be more reliable. Resale will be better. They are ultimately both bowls of vanilla ice cream, so to me it makes more sense to get the Toyota for vanilla based reasons.
Granted if you aren't going to be keeping it for more than 6 years the Subaru becomes more compelling.
As for your points:
- better AWD
I am not sure this is true any longer, it appears Toyota put a lot of work into the AWD system. At the very least, it's going to be a moot point for most buyers.
-higher ground clearance
I assume the Subie will have more but I haven't found the specs for the new Rav. I did read a motortrend article that said the Rav gained an inch and a half of clearance. So it's an inch less than the Subie.
- standard Apple CarPlay/Android Auto and auto-climate control
This is coming to the Rav.
