Well for subjects that involve a lot of applying, the best thing to do is to write it out, because what I do is, for something such as Physics, I find it incovinient to type out the formula, and solve an example by typing, because I cannot hope to do such a thing on MS Word.
So yes for some subjects writing it out is better
For English I type 80% of the time, the only time I do not type, is during class or practising essays before exams. Practising essays not near an exam I will nearly always type it out. (But I have horrible cursive writing, so there is that contributing to my biasis to typing)
For notes, Math is irrelevant, memorising subjects such as Biology I would type because you can read your notes easier. For social sciences I would type it out like I do for Economics.
