It's pretty subjective but this is my favorite looking 5th gen among all the in service jets and demonstrators that have been designed so far (besides the YF-23/F-23). It's like the F-35 but not so "fat", instead it's more "elegant".
It is also pretty interesting that, although there are some design (like the DSI or canted wing/stab edges for ex.) and size differences, Kaan and J-35 will end up looking pretty much alike from a distance due to a mixture of "F-35 and F-22-ish" design choices.
Also, although the IWB is not exactly the same as that of J-20 (as it's been speculated to be), it's pretty much close at least in terms of surface area so this enables commonality of carriable payload. Which is big for a bird of this size (KF-21/F-35/AMCA class).
