Though you have given some strong advantages that EF would offer us but I would still go with Su-35 option though I am too reluctant about Su-35 and Russia and you can ask
@batmannow, that is what we were discussing, the possibilities how Russia can screw us, where he was in favor of Russia.
First of all Indians never rejected Su-35 they rejected Mig-35, in MMRCA competition (Russians entered with Mig-35). As far as you are saying that we can use the same armament that we use on our F-16 indeed that is an advantage but you know USA and west is very reluctant in supplying us the latest versions and once uncle sam says no there is nothing KSA, Turkey or UAE could do even if Brits want to they wont.
Secondly as far as F-35 is concerned we can still ask for them if we are going for the N deal (which i am against). But believe me we wont get any western 5th gen aircraft that easily or early.
Thirdly though you have a very good point about training our pilots and crew on Saudi EF but I am pretty much sure Russians would offer us (if we go for 50+ Su-35) to sent a contingent of pilots and technicians who can train on Russian Sukhois. Even if that is not offered we can do a crash course about flankers with China. JK about the term crash course what i meant was we can train our pilots and technicians on Chinese flankers.
Lastly I am of opinion that even if we are unable to get Su-35 because there are news that Russians are yet not ready to give us their deadliest 4+ gen aircraft, we should go for Chinese J-11D or may be a mix of J-11 and JH-7. I am saying this because with PCEC becoming reality we are bound to get even closer to China and hence US and west would try every possible thing to stop that. Believe me China is the next big thing and even USA and Europe have realized that. And who knows if we go for the Chinese option then we can use the same weapons on our flankers that we use on JF-17 and who knows may be on J-31 as well.
That's it!, this what i think you have all the reasons to disagree.
