I just find the saving mechanism frustrating to use compared to vim's as an entry level user, and now as a mid-skilled user I dislike how featureless nano is - when I was first learning how to use the terminal I hated having to edit anything as I was pretty much force-fed nano with no alternative provided, but on finding vim and remembering literally 3 things (:w, :q and i) everything became so much easier, but I definitely do have an extra bitter taste left about not being told about something much easier to use which irked me when I saw someone preaching how amazing nano is

I also really don't get the hate for vim when remembering 3 things gives you as much/more functionality as nano and is a starting point for so much more functionality - intuitive doesn't mean featureless and don't try and pretend nano's shortcuts are the same as 99% of other editors (text or otherwise), in fact they're totally different, making it less intuitive
