JF-17 vs Gripen vs MiG-21 Thread 2

Since Mpacha closed the first one, this is a continuation.

Summary of first thread:
Ocean Boy and aliases claimed JF-17 is superior to Gripen because of DSI

International amalgamation of members replied and unanimously agreed
Gripen is superior to JF-17

however in terms of MiG-21 vs JF-17, it was half half. Perhaps with MiG-21 even edging out the JF-17.
