It's hard to hate nano, but IMHO there also isn't anything to like in particular either. It's basically a TUI notepad. It's there, it lets people edit files... and that's pretty much all there is to it.
You can use nano without having to read anything about nano. That might be the only thing that is better about it than vim, but it's a damn important thing.
I have zero patience when trying to make small adjustments to files, which is what my command line text editor should be for. Nano just has everything at the bottom in case you forget (I do, frequently) so the workflow is ridiculously streamlined for me
Well, if you dd+p you paste it back again, and then it's in the clipboard so you can p it in other places. In any case you can u(ndo) it without issues.
yy to copy, dd to cut, p to paste. Need to move 5 lines at once? No problem, move to the first line and use d5d, and p to paste it. Vim gets a bad rap for being confusing, but it's so fast to move text around once you get the hang of it.
I like nano because it has worked any time I needed it. I don't dislike nano because I'm not good enough at Linux to have ever run into its limitations
