I would personally recommend using vim bindings in emacs, as they are (in my opinion) easier to make sense of and more intuitive. However, I'm sure this book is a great resource for all the other stuff and it seems very well put-together.
C-f, C-b are English-centric, and would be totally nonsensical to a user of a different language.
Intuitive is hard.
Really great.
There's nothing wrong with Vim, and nothing implicitly wrong with using Vim shortcuts in Emacs so long as one is aware of its Fortran in any language style limitations.
What I like most about emacs though is that I rarely have to do repetitive tasks because I can write a bit of lisp code to do them instead.
