@pinkflaps,
Maybe you are looking for more guidance BUT I have answered your question already on the Qatar thread...
As I told you there , Flydubai is a low cost with only B737 and Qatar is a state airline with medium and long haul fleet.
You can not compare the two , it's two totally different business model and kind of operation and the career opportunities are also very different.
Read the comments on both airlines , compare the conditions , and choose what kind of life style and career you want and then you will have our answer.
Nobody can make the decision for you , it's your life and you only have one so make the right choice...
Good luck
