Who is considered the best rival ace pilot in the community?

Note: I am an Ace combat enthousiat, not by any mean an expert in the games, but i quite like them, I've played 4, 5, 0 and X way back in the days, then the series kinda went out of my radar for a while, though i would still keep an eye on it from a distance, and I've finaly returned with AC7 last year. No need to tell you i might have forgotten a few obvious things or even have missed them completly, so don't be too harsh on me if i make mistake. :)

​

In my fuzzy memory i remember mostly 3 rival Ace pilots in ace combat Yellow13 in 4, Mihaly in 7, and Pixy in 0 I can't remember if there was a rival in 5 and i am pretty sure there wasn't in X (I've replay it during containement)

For me the obvious pick seems to be Yellow13 from which i still have vivid memory to this day, i think he has the better story, and he was quite challenging to fight during the various mission.

Pixy didn't leave that much of an impression on me, Mihaly is an other big one, being very challenging during gameplay (I feel like it was the most challenging but maybe it just a trick of my memory as it is the most recent i've have fought) though i feel his story was a little more messy and by the numbers than yellow13.

So personnaly i Would say 1st: Yellow13 2nd: Mihaly 3rd: Pixy

I am very curious to see what the community think of that question.
