I read the opposite, exactly from pilot interviews. It flied like bitch, specs were mostly exaggerated, their engines still have a low life span, Russians lack metallurgy skills to develop single crystal blades, and seeing at their development trends, they even wont be able, even china isn't capable of it.
Biggest drawback is that that the thing has supermanuverably only while empty(that we see during airshows), while loaded it doesn't have anything of it, it even cannot turn(9G) unlike other older gen aircrafts including the F16.
F22 remains still the only gen 5 jet in my books. F35 is a beta test still.
Sorry mate, but answer sounds like a pile of BS and some copy-pasted text from some self-proclaimed "expert".
Mig had superior turn rate, accelerated faster, and combined with HMS + R-73 it was unbeatable at short ranges. Neither aircraft carried long range AA weapons. F-16C had slightly superior radar, but Mig had IRST which gave it an advantage. That's what German pilots said. Besides let's not forget that this was downgraded export Mig vs. US non-downgraded latest gen F-16C.
Besides, Russia HAS monocrystallite turbine blades which are present in few AL-31 variants and I think that RD-33MK has them as well, since RD-93 has them for sure. AL-41 has them 110 % as well as civilian PD-14 and its variants. China might have them too since they shamelessly copied (stole) many Russian, British and US technologies. So, your claims are not correct again.
The other thing about Mig's lack of maneuverability when fully armed is only partially correct. When lightly armed, Mig-29 can without a problem pull 9 G's and pretty much the same goes for F-16. They both belong to 4'th generation of fighters, although the "ultimate" Mig-29 variant (Mig-35) belongs to 4++ generation, meaning that it's much more advanced than 4'th gen fighters and has close characteristics to a 5'th gen fighters.
For now F-22 is the only active 5-th generation fighter, but T-50, J-20, J-31, F-313 and others will follow very soon. Besides, "stealth" is a Russian technology and without Ufimtsev's work there would be no US stealth bombers and fighters, or at least there would be no such for a few decades. These are just plain facts.
F-35 is a failed program. Accept it. It's not an maneuverable aircraft, its stealth is questionable and its combat performance even more questionable. So far the whole F-35 program burned billions of $ and the single unit will cost almost 200 million $, which makes it not only a ridiculously expensive aircraft, but also the worst possible value for the money. Even if USA solves many F-35's issues, this will further increase aircraft's price to well over 200 million $.
