Attack on Titan definitely. It's my 2nd favorite series of all time, Season 3 Part 2 especially. Some of the best moments I've ever seen in an anime. I didn't like the later seasons as much, but they were still very good.
Diamond is Unbreakable is great though, and it's my favorite JoJo arc. Kira is a great villain.
It's been a bit since I've watched it so I won't be able to get too detailed, but I didn't find much about it interesting. The characters and the story fell flat for me.
And yeah, Romance is not my preferred genre. Dress up Darling is probably my favorite romance focused anime I've watched.
Shield Hero was the worst anime I have ever seen. It has an extremely generic Isekai storyline, pedo bait, (mostly) annoying characters, awful writing and nothing to redeem it.
This is just my opinion though! Sorry to any fans of these 2, but they weren't for me.
