i have worked both in qatar (2006-present) & saudi (2000-2006) ... if i were you i will choose QP over Aramco though Aramco is 40% higher but you will definitely not enjoy your life in Saudi.. a very boring place and lots of restrictions i should say...if you are ready to live an abnormal life with more money inside your pocket then choose Aramco but if you really want to enjoy life, i strongly advice you to accept the offer from QP... but still it is you who will make the final decision.. just hope you make the right decision... as i said being happy is not all about money...
