MK watched all his videos. He gives some good basic aerodynamics lessons quite simply and in a meaningful manner.
I think the point about not properly area ruling the wing-fuselage of the JF-17 is true. But then this is offset by the side intakes, the bulge just immediately after the intake and the LERX, all of which compensate but perhaps not 100% (meaning better area ruling would help the Jeff).
I think the commenter also has his biases, he loves delta canards and can't really see another design choice as a true counterpart. For him, the delta canard gives 20% superior performance (which is open to debate on exactly what parameters that is true).
Truth of the matter is that the JF-17 does an amazing job with the limited resources and is, in terms of actual combat capability, competitive in BVR and WVR against any 4.5 gen fighter. The only issue that Pak has to worry about is the advanced EW of the Rafale. Pak has not faced high tech EW so far against India.
Rafale's advanced active cancellation and aircraft masking are serious concerns, but the Youtuber in another of his videos says we should take that Rafale capability with a bit of salt, so perhaps I am overplaying this. The Meteor is the other concern and Pak has already countered that.
With the recent acquisition of high tech radars, Rafale's active cancellation and other EW capabilities will be significantly diminished. I hope this works to Pak's advantage.
In terms of aerodynamics, the Rafale is not optimized like the Eurofighter for high-high performance. So it will have an advantage but a marginal advantage. The only concern is when this marginal advantage is combined with the Meteor and the EW, it may (or may not) become a bigger advantage.
All this of course if India can do a great job (an not an average job) of operationalizing the Rafale.
