With PCs I prefer Linux but it’s not great to game on Linux. With phones, you won’t see a huge performance difference between android and iPhone on any phone that’s less than 5 years old. Custom ROMs on android don’t make a huge difference either. 

Dealing with a rooted and degoogled phone and trying to use google pay was an eye opener. So many apps just don’t function if you are degoogled or rooted. 

I would still be using a Pixel if they didn’t sell out and focus all of their development on useless woke shit. Google software used to be great, but modern android is just absolute trash.
