Something to be considered for AMCA - limitations in stealth coatings.

At extremely high altitudes, the U.S. Navy and Marine Corps’ versions of the F-35 jet can only fly at supersonic speeds for short bursts of time before there is a risk of structural damage and loss of stealth capability, a problem that may make it impossible for the Navy’s F-35C to conduct supersonic intercepts.
Both deficiencies were first observed in late 2011 following flutter tests where the F-35B and F-35C both flew at speeds of Mach 1.3 and Mach 1.4. During a post-flight inspection in November 2011, it was discovered the F-35B sustained “bubbling [and] blistering” of the stealth coating on both the right and left sides of the horizontal tail and the tail boom.

do consider the fact that f-35 b and c are in service with the marine corps and the navy. These 2 variants are exposed to the sea and that affects the coating adversely

We can’t really compare f35 with AMCA there are subtle basic differences between them the cross section of f35 is thick aerodynamics in design were neglected for stealth in design, the swept angle of the wing is low compared to AMCA & the fat bird doesn’t even super cruise and many more thus all pointing towards higher drag due to design preferences which could be the cause for the reason for bubbles and blisters if we recall even f22 speed is capped at mach 2 due to the same reason(the surface temp of fighter increases due to air friction).
