How about buffing Su-27SM?

In all honesty, I predict this thing will probably get foldered like the J11 and J11A once they add in some other further development of the flankers, something like the Su-30SM2 or the Su-35S.

Absolutely, no doubt at all that su35 is the far better fighter, a much better avionics suite, better radar and passive detection systems, also arguably a much better dogfighter, the loss of canards massively improves its energy retention aswell as apparently more thrust, so a Su30 but doesn’t lose all of its speed and can sit at its optimal rate speed.
