I use vim (or vi on some antiquated machines). Others in the company use Emacs, Visual Studio, Qt Creator, Sublime, and so on. When the company was more startup-ish, it was a matter of individual taste, influenced by their IDE/editor. Giant checkins of mostly whitespace changes eventually became an issue, and were banned. Years later, and the code it mostly spaces, but I see places in the code with random tabs in between, every now and then. For my case, vim handles a bunch of auto-format and auto-indent options turned on, and replaces the tab key with 4 spaces, unless I'm editing a Makefile (where commands to execute are preceded by a tab character).
