Yet I resent every time I have to use grep, instead of a tool integrated with my IDE. Certainly those baroque old tools have their detractors too. That they survive so long (like vi and emacs) due to cults, not objective evaluation?
I use sublime text as my main editor, but I still need to use vi from time-to-time - e.g. when ssh'ing to a remote server. That's definitely an objective need, unless you can offer an alternative that is just as widely available.
