Open Street Map absolutely suck

You have upset a lot of people. OSM is an awesome alternative to Google Maps, it's basically the Wikipedia equivalent for mapping where everyone can help contribute by adding locations and such. Particularly for densely populated areas, I find it to be very accurate, and there's even support for public transit!

I wouldn’t consider using a slap-stick repo like F-Droid

You have somehow upset even more people. F-Droid has soooo many good open-source apps that are stable and they usually work far better (and look nicer for the most part) compared to proprietary options. CoMaps is a good client for OSM and arguably has a nicer interface than GMaps, and you can install maps offline which is super convenient! Kvaesitso is a nice search-based custom launcher that is much better than the stock one for my purposes, and Lawnchair is another good option if you want something closer to vanilla Android. More great FOSS apps:

• Breezy Weather
• Etar (calendar)
• Auxio (local music player)
• Aegis (2FA codes)
• Chrono (clock)
• FluffyChat (Matrix client)
• HeliBoard (keyboard, the BEST ONE! even has accurate suggestions and glide typing!)
• various self-hosted bits (Nextcloud, Immich, etc.)
• KDE Connect and LocalSend (AirDrop+ that is cross-platform, the former is preinstalled on KDE Plasma)

And games on F-Droid are a bit more lacking, but here are some nice ones I found:

• Simon Tatham's Puzzles (all the puzzles you could want, quite fun!)
• Breakout 71 (fun game that is quite neat)
• Retroarch (emulation, my device can play up to PS2/GC and Wii, but higher end models can even do Switch!)

Plus, you don't have to use the F-Droid repos. You can use third-party repositories like IzzyOnDroid or similar with the F-Droid client!
