The bugs were massive and glaring in the early days. Things as simple as getting a notification would sometimes completely blank the rest of the screen. Since then, random slowdowns and slow animations have only gotten worse.

Beyond the core platform, Google's apps (which feel like an extension of the core) are just getting worse too. Android Auto for phones has been replaced with a terrible driving mode implementation. I recently used voice search to open an audio app in driving mode. It helpfully opened the app on my tv at home instead of the phone that was in driving mode miles away from home.

Everything is more disjointed and less functional than before. The little helpful four icons at the top of the app drawer? That was an amazing feature a few years ago. It'd always highlight one of the ones that I was about to use. Now, it fails 100% of the time, no matter how obvious it should be.

Things that used to be easy to do with the notification shade are now more confusing and take more steps than ever before. Its an awful mess, and this is literally the first time that I've preferred ios on my ipad over the Android UI.
