That really is a question only you can answer. You say you want this to be long term move so the question you need to ask is can you live for a long period of time in the Middle East? For me the answer is simple NO! So I would choose EZ wait a while and get my command and then sit there fat dumb and happy for the rest of my career, only slight floor in that plan is you will never get a decent contract offer from them as an FO! If you can afford and are willing to accept a
deal for a few years then EZ might work out. I know nothing about NOR so can't advice. Having worked for one of the other big 3 ME carriers wild horses would not drag me back, but if you can live with it then it has many benefits.
