I'm gonna go away from the more intellectual experiences offered before me, I've seen most of those shows and I liked them all (apart from the few I didn't watch) and I'll possibly make myself hated in the process but bear with me:
Just finished watching season three of "Attack on Titan" and season 4 is ongoing throughout this year. It even got my girlfriend, who hates anime, to really get into it. It doesn't fall into that normal trap of anime; to have people screaming for 10 minutes about inconsequential stuff, in the middle of a fight. It also doesn't have those stupid characters that western audiences (myself included) hate i.e. maids, catgirls, cutesy stupid animal sidekicks stuff like that. It's honestly a really good expose on PTSD and the real effects of war and has a deep fantasy lore that isn't tolkien in nature!
Apart from all that it's really edge your seat stuff, some of the action scenes had me sat there literally sweating. Also quite a few characters die in it so that makes it different too. It adds to the action because people might not have plot armour!
