Overall, ignoring the kind of device, it's my preferred linux distro, followed by android, followed by other distros, followed by windows 7.

I wish Linux mobile was ready for what I need, but there just isn't app parity currently.

The learning curve switching from win7 to whichever version Mint Linux was on at the time was acceptable. No harder or easier than picking up android for the first time once installation was finished. Easier than when I've had to dick around on iOS. I can't say what the switch would be like now since only my laptop is running dual boot with 10 right now, and I never open it at all. I kept the windows partition for some of the crap with self publishing that isn't as easy on Linux, but I find there's no motivation to boot to Windows lol.

I really like excels android overall, and I used to run custom roms on everything, and had a ton of fun playing around like that. But Google has made android suckier, if not sucky enough to switch to iOS or put up with the flaws of mobile Linux (though it has been a while since I tested anything in that regard). So, as long as android is essentially controlled by a for profit company, I don't know that it could be my favorite os.

Linux wise, Mint is the tits. Yeah, there's distros that do some things better. But damn, I've thrown mint on all kinds of boxes and then just got to using it for what i want to do, not fiddling around with things. The bullshit canonical pulls isn't an issue, and that's nice. Popos is pretty similar in that regard tbh, but I prefer the default looks of mint better. That's a niggling little thing, but such is life.
