The EFT or the Rafale, neither are worth the money IMO. F-16's newer blocks (currently an upgrade in works), make it on par with these planes. In fact, the EFT has been handed its rear in a plate multiple times. A few times, by F-16's block 15's!! So not to offend anyone, what the fuk does one get that you don't get in an F-16 block 60++????
The answer is NOTHING. The PAF and the Israeli Air-force's romance with the F-16 is actually justified. Where else do you get one of the most combat proven and hardened jets in the entire world for 60% of the money you'd pay for the alternatives (Western alternatives like the EFT and the Rafale's). The answer is you don't get the durability, quality and advancement in any other platform, and affordable maintenance.... period!!
So if the Pakistanis wanted to move onto something else, IMO, the best option would be a one time large JV or an investment (TOT) to acquire the J-10 C version. Call it a JFT block IV. And add a few more upgrades to it. BAAM, you are in EFT and Rafale's category and at which point, it would be a Pakistani platform, with serious future R&D and upgrade options and ability to integrate additional weapons, and advance however Pakistan feels the need.
If things go well in the near future and Pakistan remains a democracy and a growing economy, I can see Pakistan integrating French missiles, or even AMRAAM's and Sidewinders onto this future JFT block IV jet (they did integrate the Sidewinder onto their F-7PG version so the experience is already there).
With such acquisition, Pakistan can keep the F-16's as a supplementary platform but she won't need to buy another platform if Pakistanis continue internal R&D for the future. The version after the proposed JFT block IV, could be a stealthy version locally built also (JFT block V).
Then the only other platform they would be acquired, would be the J-31 when it becomes available in 2019-2020. Perfect strategy, independent of any future purchase by building advanced versions in house and integrating weapons from China and others as needed
