For desktop computers, either Windows or Linux. Windows on my main computer since I rely on so much Windows-only software (MS Office, Many Games) despite the BS that Microsoft does to windows in new versions, but Linux has gotten way better lately, especially as it picks up new users as Windows declines. MacOS to me the worst of both worlds when it comes to lack of software support and corporate BS
For Mobile, definitely Android. Android is what I wish Linux was for Desktop computers; Loads of software you can get from many places, open source, and not locked down. It’s mainly the way it is because for Mobile OS’s, Microsoft was spending too much resources shooting itself in the foot with the Zune than to make the necessary improvements to make Windows Mobile to be competitive, and by the time they realized their mistake it was too late. iOS is such a pain in the ass for me to use due to how locked down it is, and while it has more software support than MacOS, its locked down nature and being mostly restricted to getting software from Apple means that several apps that I rely on (including a few apps not on the Google Play store) will never be available for iOS. I also like to see where every single file on my phone actually is
I have KDE Neon on my Laptop and Bazzite on my desktop/server but I want to switch it up a bit.
I’d like to get a TuxedoOS laptop with specific hardware fix and I’m also thinking about EndeavourOS these days to try out for a couple of months.
For the server I think I’d probably to just go for Ubuntu because it’s piss easy to manage because of the experience I have with or just the Fedora KDE. I really like Bazzite though for all the batteries included.
I prefer manufacturer Android on my phone but I hate it with a fiery passion. I have an uncommon Xiaomi phone and the memory management is abysmal where they kill activities almost instantly after they go away from view. I like it because the battery life is amazing. I’d prefer to use LineageOS but it’s not supported on my phone.
