Because Super Sukhoi also means:
- far higher operational costs because of even more heavy class fighters
- 3/4 of IAFs fleet of the next 30 to 40 years will be completely dependent on Russia, be it for upgrades, cost increases, or even weapons
- that IAF is limited to Russian and Indian weapons only, since no western manufacturer will allow to integrate advanced weapons to Russian radars and systems (especially with the recent issues between Russia and NATO)
- that HAL, or the Indian aero industry as a whole will not get any modern technology, or production input, the main reason for MMRCA (simple example is SAMTEL, that would keep producing some MFD's for MKIs, rather than modern IRST/electro optics, or HMS + most likely MFD's for Rafale)
- far less financial benefits for the Indian aero industry, because of the high offsets clauses of the MMRCA competition

You might not like the Rafale, but you can't argue against the reasons of MoD and IAF with MRCA / MMRCA wrt to industrial and tactical benefits.
Wrong, the RCS will be reduced pretty much the same way as it was reduced at the Su 35, or at the Mig 29Ks, by adding RAM coatings. The only difference that the Super 30 will then have to the Su 35, is the bigger cockpit section and the canards, which both adds to the RCS. But it still will be far lower than today and the advantange of not using big fuel tanks will remain an advantage for the Flankers anyway.
