Depends on the career that you wanna build. Or more specifically the clients that you want to have working for.

JEE is more enterprise oriented, used in lots of big companies.

I personally would recommend you Django, it's more flexible in my opinion.

Also I prefer Python 100 times over Java, but that is very biased on my side :)

P.S. I am mostly using React + NodeJs (ExpressJS), again personal preference here :)
