My sense is that the answer to this may lie in how long you intend to be based in the Middle East.

Assuming you plan to be there for the foreseeable future.

If you can earn enough to get GGL, it is worth considering and switching for the vouchers, jokers and helpline. Once you got over the hump to qualify, it looks manageable to maintain based on what you described.

If you are more around a comfortable gold , I don’t think there is much value in maintaining two one world statuses. Have you considered adding a ME carrier to diversify your choices? There may also be a Turkish Airlines status match available for a star alliance option. The onboard product is very good, although the rest is not optimal in terms of customer service.
