This preference seems to depend a lot on where you come from. Having come from Scheme / Lisp (same as some of the original Julia developers AFAIK), I find I prefer the REPL in Emacs for coding. I do use Jupyter quite a bit for running simulations, doing data analysis, etc. For me, the main reason to use Jupyter has been (i) interacting with sessions on remote machines without needing to bother with X, and (ii) being able to easily incorporate LaTeX and share whole documents (math + working code) to collaborators and students.

PS I have tried Pluto and find that I don't like it very much in its current form, though I kind of like the idea.
