Gulf Arabic vs Saudi Arabic

Good, with some adjustment. Gulf speakers and Hijazis understand each other well, but Hijazi sounds closer to Egyptian: b- for the present, 7a- for the future, eesh for "what" and da7een for "now". Gulf Arabic has abi, waayid and il-7een instead.

Which one should you learn?

Hijazi if you are heading to Jeddah, Mecca or Medina. Khaleeji for the UAE and the smaller Gulf states. For Riyadh and eastern Saudi Arabia, Khaleeji is actually the closer of the two.
