Who cares what "most" of them are about, nobody is forcing you to watch shitty anime series, I usually avoid all the high school shit, anything with the tags - romance, harem, and my personally most hated SLICE OF LIFE needs to be avoided like the plague as they are usually cliche, boring and rehashed shit, its the same shit in all those series, and only normies ever watched them.
There are exceptions though where the series has some of those tags but doesn't really revolve around them e.g. Code Geass (one of my favorites)
My favs would be:
1. Death Note (Kira is another character I idolize)
2. Code Geass
3. Berserk
4. Kuroshitsuji (Black Butler)
5. Aizen (not an anime, just a character from Bleach, that I idolize so much that he ranks as his own series, literally only watched bleach for Aizen)
The funny thing I find is that there are no actually existing humans that I idolize, but for some reason their creations are easily admirable, I think its because humans limit themselves so much trying to "fit in' in the world, and the outlet is "their art".
