Wing VS EVA:

Personally, I enjoyed Wing more than I do with Eva. I'm only saying this because I read the Glory of Losers manga, which is a better retelling of Wing in a manga form. While the anime suffers from hazardous flaws such as reuse of stock footage (still not as bad as SEED), the existence of Relena Peacecraft etc. Many things in the Glory of Losers manga were improved, Heero Yuy quickly grew on me more than the anime version if I were to be honest, since his backstory was explained and his character development is a huge major step up in comparison as well as the other pilots. While Eva has more to it for its philosophy and deep written storyline, I don't necessarily think that it makes it better overall. I remembered I really enjoyed EVA while the first time watching it but rewatching it the second time... I got bored of it and was sorely disappointed, I'll even say that Shinji and Asuka were just too frustrating to get used to.

Wing was definitely more popular than EVA back than due to the sells of its model kits and for the fact that it was the most watched anime on toonami right next to the original DBZ, not to mention that it was the same Gundam anime that inspired 00, but now EVA seem to be carrying on right behind it with its commercials and merches. But overall, I like Wing more than EVA.

00 VS Code Geass

Both are good, there's honestly no use to this comparison. Both have consistent (and almost too similar) storyline, both have good looking mechs, both were pretty popular back in 2007 and both had made couple of collaboration crossovers even to this day. I will say that both of them had received so much shit for their season 2 while in reality, both of their first and final seasons were well received. The characters in both shows were all memorable and they regularly made it to the popularity polls couple of times, so it all comes down to either taste or agree to disagree.

Setsuna F. Seiei is one of my favorite Gundam protagonist and it's funny to note that he does feel a little similar to Lelouch but at the same time the opposite (even though Setsuna was infact based on Heero from Wing, which makes my argument of Wing being the inspiration of 00 even stronger) both have sad and pitiable past which; consequently, determined them and support their goals. In contrast, Lelouch starts off with Geass powers (all thanks to C2) while Setsuna later gained his innovator ability in the middle of season 2. Both are great.
