Development TIme

So I use unity also but thinking about switching to Unreal completely so ive been asking and reading other views on the engines. I said why unity and one person had said he would show off his progress of a couple months to his freinds using c++ and they couldnt say anything most people say unity is for speed not power. Would developing in c++ could i get the same progress as c# in equal time or does c++ require more code. p.s im new.

Thanks for the response and no didnt read that section ill look into it thank you
