Given the general state of development in these Arab countries it's likely that Soviet style training and equipment are the best for them. As an example the talent pool for a fighter pilot is quite shallow in these countries, so they struggle to fill the seats of the planes they get, whereas the talent pool of potential SAM battery commanders is much greater and the training demands are significantly less. So it is better to have a lot of SAMs than a lot of fighters, as an example.
But fuck it, I'm going to be contrary! After the 6 Day War Egypt and Syria abandon both the Soviets and Americans and go balls-deep with Britain and France. They sell as much Soviet crap as they can and buy export model Lightnings, Buccaneers, Mirages, Bloodhound, Thunderbird and crotale SAMs, Chieftain and AMX30 tanks and other AFVs. This is all backed by extensive support arrangements including training.
In 1973 the Red Top proves itself to be the best AAM in the world and the other Anglo-French stuff performs well but Israel survives.
