evil-mode all the things + general.el for defining custom bindings. I am a long-time vim user, but do use emacs for things like org-mode. I prefer modal editing and vi-style navigation to emacs' defaults, which feel especially cumbersome if typing on a phone in termux for example. However, I don't attempt to completely vimify emacs and remap all the bindings. I tend to use the defaults of each mode and only remap when stuff is overridden by evil.
That said, like anything, delving into emacs takes time. Whether or not it is worth the effort depends on your needs really. For me, it has been worth it to make use of versatile tooling such as org-mode.
It's always nice to find another user of the almighty orgmode in the wild!
