I am sure some pilots really enjoy FD. If you want to spend most nights home like at a Euro LCC, FD would fit the bill. If you have no interest in flying anything but the 737NG for the rest of your time at FD, then that airline would suit you. If you want to fly to some somewhat dangerous (but exciting!!!!) destinations in war zones, then FD would be for you. If you MUST live in Dubai, FD would work.
But, if you qualify for EK, QR or EY (and all are hiring), then FD would be the last choice I would consider.
