Might as well apply to QR, the unamed airline and EK (if you want to fly a widebody) and if you want to work in the ME.
Better pay, and considering most airlines in the desert have similar conditions, you might as well make more money, unless DXB is where you want to live and you don't want to work for EK...
Also consider why you'd want to go from a a320 FO to a 737 FO (year 1) at FZ?...You could definitely see command earlier if you stay on the a320.
