We here ( amateurs ) in M.E prefer Sukhoi comp more than mig , i think defencetalk and militaryphotos guys also have that opinion .
We are all amateurs... and it is just my opinion really.
The Flanker is a good bird, but I think Sukhoi will struggle to produce the numbers needed for demand.
No disrespect meant, but the new regime in Egypt is largely an unknown quantity and I think Egypt is more likely to be offered Su-30MKK or something similar rather than their brand new Su-35s, and I suspect if you want the best technology that Mig is rather more desperate for a sale than Sukhoi are and that Mig might even make offers like let Egypt produce components, or even joint development of a light 5th gen fighter if you really want to spend money.
At the end of the day the Mig-35 can carry almost anything the Flanker can carry, it has 10 wing pylons and a centreline pylon for stores, it doesn't have the flight range of the Flanker but inflight refuelling make that null, and of course if you want to expand into carriers a Mig can be modified to take off from smaller carriers than the Flanker.
The larger apature of the Flankers radar is countered by the fact that the Mig will have a full AESA system and I think the IRST system of the Mig is probably better than the Flankers.
The Mig will likely be cheaper to own.
And like I said, the Mig is seriously underrated.
Of course a mixed fleet of Flankers, Migs, and Yak-130s....
