I have lists like "Places to Work" which is a list of all the nice coffee shops and places I like to work out of (currently have 200). I star hotels + AirBnBs I'm staying in, and bookmark a ton of things. I rely on it for public transportation. If I could only pick 3 apps on my phone, Google Maps would definitely be one of them.
I do wish there were better alternatives and I hate being overly dependent on one company. Unfortunately the open source alternatives like OpenStreetMap don't really even compare.
