Well F-35'A with block 3F software can attain 9G with a full internal payload and fuel, Rafale can't do 9G with a comparable load.
Actually it would be a small miracle if IAF itself orders more Rafale regardless of what non sense chatter is out there, I fully support the need to bring Rafale number to 90-100 i.e 1 sqd for every air command.
The Carrier competition is a toss-up and the SH block- 3 is better suited for IN.
The F-35 will outsell the EF, Rafale, Gripen, and every other 4.5 gen fighter put together. It may not be the best A2A fighter or the best ground pounder, but it combines a mix of abilities while bringing next gen sensor fusion, sensors and tech. It's a single engine multirole fighter and it will full fill that role 100% and will do so quite well for decades through continuous upgrades. In any real combat scenario VS anybody else combined with the F-22, the US F-35 will have a significant edge while deploying it's widest set of tools. Combine that with a wide set of AFs from Japan, Israel, SoKo, Norway, Denmark, Britian and so many other operating it, by 2021-22 the tactics will have evolved to a stage where any pilot would be confident taking on the toughest comers.
Now whether sales are acheived though bribes, through nations sucking off uncle sam's or any other means is a matter of no concern. Even Rafale export sales so far are nothing but shady including the sale to India, so it is wiser for the Frenchies to focus on the aircraft's merits and not the methods used for a sale.
IMO F-35 should the best candidate for the SEF competition since the timelines are perfectly fine for this to be acquired. It's either this or 200 more orders of LCA MK-1A or MK-2.
