YOU GOT GOOD OFFERS, NO WONDER WHY YOU CANT DECIDE.
FIRST OF ALL DROP 1 AND 2
NOW YOU HAVE TO CHOOSE JUST BETWEEN 3 AND 4.

MY ADVICE TO YOU WILL BE 3 AS THE SALARY IS VERY GOOD AND WORKING HOURS IS BEYOND GREAT! YOU WILL HAVE MORE TIME FOR YOUR SELF,AND NOT ONLY WORK WORK WORK!!!!!

IN THE END ALL UP TO YOU.
