How does that work, and with which editor settings? If you simply set the tab width (tabstop) in vim, things go south.
Say you have a function definition one indent level in, then 22 characters of text. You more want to align the next line to that. How does that work in practice with tabs?
The obvious way with tabs and ts=4 would be 6 tabs and two spaces(one tab for the initial indent, the rest to match 22 characters). But then someone with ts=2 comes along and barely gets half way there, or someone with ts=8 who overshoots by a lot.
That's not how you should mix tabs and spaces for alignment. You use the same number of tabs as the previous line, and then fill the remaining width with spaces. That way, when you change tab width, the alignment spaces will always start in the same column as the line they're aligning to, regardless of the tab width.
Do most editors do that by default? If so, that's great -- if not, it's just a downside for tabs, if you need to hit enter, backspace out the automatic indents and then press space 30 times rather than just hit enter and have it aligned automatically.
vim seems to auto-insert tabs when you hit enter mid-function definition, at least with standard settings.
That seems like a problem with Vim, then... Typically I don't align at all, so I'm not familiar with editor behavior for alignment; I prefer to just indent one level deeper.
Setting
tabstopandshiftwidthdifferently is basically legacy braindead behaviour. It is going back to the logic of tab is just a way to compress spaces. If you are doing that then you have all of the problems of both tabs and spaces.As for alignment the easy answer is don't use tabs for alignment. Use tabs for indentation, if you want to align something use spaces for the alignment past the indentation. Lemmy seems to be breaking code snippets right now but I have a really old blog post about this.

The post is a little out of date when referencing the style of my blog but the C example shows alignment. If you can resize the browser you can see that the indention changes from 4 to 2 as the screen gets narrower without breaking the alignment.
