I've degoogled quite well, the only real google services I continue to voluntarily use are YouTube and Maps. Although I don't use YouTube itself, I mostly interact with it through third party apps (i.e SmartTube or Invidious) and with Maps... well... nothing comes close. I wish there was a decent competitor to Google Maps but there isn't. I tried using Apple Maps but it lacks all of the crowdsourced information that Google has access to.
Even with Google Maps, I find the UX of Apple Maps to be superior.
The worst part is how when you’re on a trip and move to another app and back, Google Maps will wait 5-10 secs before showing you the trip you’re literally on. Instead it prioritises the unwanted “what’s on” box.
I’ll use Google Maps for reviews, and Apple Maps for everything else.
