I think most people who strongly identify with tools like vim do so out of a sense of identity-building to "be the kind of developer who is good at vim" / embody some kind of aesthetic or in-group signal moreso than an actual desire to be more effective at getting work done.
As long as you don't have some kind of stochastic or >5s impediment taking you out of a state of flow, most developers' productivity is going be vastly more influenced by their knowledge, understanding, and ability to focus on the problem they are working on than the marginal difference in time it requires to perform some navigation or editing task. Which is not to say that vim is bad or that you shouldn't use it, but that it's just a text editor and if you get triggered by someone not liking it or thinking it's more trouble than it's worth, it might be worth taking a step back and thinking about why it's something that triggers an emotional/defensive response, rather than the kind of reaction you'd have to someone liking strawberry more than vanilla.
