filled to the brim with philosophy doesnt make a mecha show over the top
TTGL is a super robo show, its key words are hot blood, over the top, action packed, funny, and... bouncy
Like how Real robo shows should be angsty, a bit realistic, talk about the brutality of war. etc.
Or Hybrid robo shows normally have tons of philosophy, reference to religious and myths, etc

There are many exception, but that's the basic idea

TTGL is one of the greatest shows among super robo shows, since it archived all a super robo show needed
Eva is one of the greatest among its peers, which are hybrid robo shows (personally I like Fafner much more than it, but not many people like that show and some keep citing its just another Eva clone)

Since its 2 different types, saying one is better than another should be purely one's opinion. Watches for yourself and decided which kind you like more
