I prefer Google Maps. Apple Maps lead me astray too often and though they are better than they used to be they still give weird directions (such as using more obscure state route names for roads rather than the dominant Interstate Higway name).
CarPlay would be a complete non-issue for me, its absence would even be a positive. I just use my phone anyway; integrating it with the car is just added hassle and one less thing I have to worry about remaining compatible 5-10 years from now.
