At the end of the day C++ will always be in higher demand because it takes a longer amount of time to write clean efficient code. So while there may be more job offerings it is not the easiest language to learn. My own feeling on his would be try each of them and go with the one you like the syntax of. At the end of the day you will be writing thousands of lines of code over your employment so you may as well be happy with writing the code for the language you pick.
