Tabs are semantic and only take one key press for movement back and forth and to delete.
If you see 1 tab you know it meant one indentation level. With spaces you have to think.
Plus with spaces you are stuck with 2/4/8 spacing(unless you reformat), with tabs you can configure your editor to your preferences.
Configure 1 tab to be 4 spaces.
Sometimes it's easier to go with the flow. I like tabs for the reasons you mentioned, but fixed-width spaces are a bit better for some reasons too. IDE's can do the heavy lifting of re-formatting indentation levels and converting tabs to spaces for me, and it means if I cat a file on a remote server regardless of the bash tab width settings or if I'm in your code or the stdlib it will all make sense.
Except that you can't because people using tabs will invariably start mixing tabs and spaces because they can't separate indentation from layout. So the code will be messed up unless you configure your editor to someone else's preferences. Also, I'm sure there is some obscure git setting to de-uglify tab users' diffs, but I'd rather not find out.
