Best distro: the one you are currently using on a daily basis.
Worst distro: windows
Best: the one I use.
Worst: the one I don’t use.
Distros are really not all that different. Just use whatever.
But Android is worst.
But Android is worst.
Depends on what you’re looking for…and what you mean by “Android.” As in solely AOSP? Or any of the derivatives to include OEM ones? If done right, Android can be more secure than desktop OS, so it actually might be the best distro, depending on what you’re looking for.
Best is obviously Hannah Montana Linux.
Worst? Difficult to say, probably anything that isn’t Hannah Montana Linux.
Best (for me) is ArchLinux, it’s never in the way and has the best wiki at https://wiki.archlinux.org, which is also a great resource for other distros.
Worst are probably Ubuntu and derivatives.
