vim mode is far, far better than any alternative way of using a keyboard (because you don't have to ever move your hands from home row). Even without vim mode, just the vim keybindings by themselves are far better. Once I got used to using them, using a keyboard without them felt stupid.

Hence my using vim mode everywhere I can.

I also created a set of mappings to give me vim-style keybindings everywhere on the computer, so I can use vim-style bindings even within this very comment I'm typing on my browser. Obviously it doesn't support the full set of vim bindings, but just the basic movements and some other mappings (like selecting a word/sentence, backwards delete word, etc) are enough to get a huge amount of value.
