I've always considered it a pillar of the medium, and something everyone had seen even if it wasn't to their liking. Short of vn adaptations and things that haven't maintained relevancy with time, I would consider it the harem. Yet, it's rarely brought up in that conversation because it has so many other things going for it.
It isn't supposed to be some extremely deep series. The toothbrush scene is/was notorious because of the absurdity, the SHAFTisms, and Nisio's writing.
Maybe there's simply too many quality options now so taste is more decentralized, but it and Madoka opened the studio to new audiences, made them a lot of money, and allowed them to be so prominent in the 10's. It was the first exposure to them for many and it's from a period where harems were the oversaturated genre.
Despite all the quirks and what gets viewed as pretentiousness, the characters are able to be well-written and give you reasons to care about them all while maintaining the fanservice. The protagonist himself has an 8-pack and isn't exempt from it either. Everyone who has kept up with the series has a different best girl, but those among them who would disparage any of them (with maybe one exception) are few.
I think it's actually antithetical to Eva- it loves otaku culture and it's shouting it from the rooftops. It managed to gain extreme cultural relevancy worldwide in many different circles despite how excessively it panders at times, because of this sincerity, whether each portion of the audience understands this or not, combined with being a genuinely engaging series. There's a lot of care in each area you can think of, from the obvious animation, to even things like all the unique OPs, during a time where gacha games, vtubers, and all these things didn't exist yet- this was the advertising vehicle, but it feels very special anyway.
I don't know how articulate I am, but this is sort of how I interpret it.
