Nationalism and people wanting to feel better than others, despite their unwillingness to present factual or relevant information to support their claims.. Intellectual dishonesty or disinformation/willingful ignorance is also an acceptable answer and is commonplace here.
For an example, we often see this with the F-35 (a strike aircraft that will be co-opted as an interceptor) being compared to the PAK-FA and J-20 (which itself may be an interceptor based on its size). Honestly, I don't know why people compare the F-35 to the PAK-FA or F-22 either, but the F-35 is still at least as maneuverable as the F-16, so the comparison might not be too far-fetched.
Comparing dissimilar items is just a common behavior for people here, and it continues even when the faults or follies are pointed out.
This can't yet be answered as it hasn't yet happened. Wait and see is the appropriate answer for this. There's not enough information to make a valid conclusion one-way or the other.
