Using or IDE or vim is entirely up to preference. True skill lies in being able to ike out every bit of productivity you can when using it. And I am saying this as a hardcore neovim user.
I won’t go to a mechanic who uses imperial measurements for their tools and rant about how they should use metric. As long as they get the job done, it’s all good.
Just because someone does not copy you does not mean they are in the wrong.
