I actually like the interface better in Apple Maps.

I agree - It's way easier to read. I was driving through Chicago recently and found Waze was really hard to read when there's a lot of exits happening all at once and it caused me to miss my exit. I'm neutral on Google Maps readability - Sometimes it's fine, sometimes it's not.

Google is far more updated and capable though

Tend to agree - Also, Google Reviews are far more trustworthy than Apple Maps' Yelp integration. If Apple Maps switched off Yelp or offered the ability to connect to Google Reviews, I'd consider moving over entirely. The other issue with moving over though is that everyone else uses Google Maps, so I have access to quite a few crowdsourced Google Lists on Google Maps.

I mainly use Waze for distance driving to monitor for po' po', Google Maps for reviews and for having an offline map downloaded and Apple Maps when I'm driving to someone's house whose address I have stored in a contact card. Each has their uses but at least Apple Maps is finally getting offline maps this fall.
