Not really, it actually came out last and below the operational requirements the Swiss air force had, but since the Swiss, just like Brazil neither can afford better fighters, nor have the threat perception that would require the best available fighters, they took the most cost-effective solution.
For most of the Gulf countries that can afford better fighters, the Gripen is not even worth evaluating, which is why neither KSA, UAE, Qatar, or even Oman thought about it. And for countries with credible threats like S. Korea, Japan, or India, it's simply not capable enough.
Feel free to name a single specific need that the navy has and that couldn't be met by the F15s, Tornados or EF s, but only Rafales could meet.
You won't find any! The Maritime attack role is not that demanding and the mentioned fighters to already offers better (EF can be upgraded to that regard) capabilities. That's why the Rafale won't be selected by your navy on technical or operational means.

UK/BAE is using their relations to your country, to sell more EFs in the region and that based on your influence and financial support. That might not work with the UAE and Qatar, since M2Ks might be bought back, but Bahrain and Kuwait are likely additions to the EF export family in the Gulf.
