I've had a TREMENDOUSLY DIFFICULT time getting fully up and running with it in terms of workflow, but the text navigation alone has absolutely made me code not necessarily faster, but in a MUCH more enjoyable way. After a while it became difficult to imagine navigating a piece of code without some of VIM's core ideas, even if in my case it is down to mostly the feature-set related to easily navigating a file.
Alas, for me then the VScode-Vim extension is doing the trick, but since you mentioned the learning wall, curious if you know any resources or can suggest a path to move past it nowadays.
