Need an Anime to Watch

Neon Genesis Evangelion, Akira, Berserk (old and newer), Mobile Suit Gundam: Iron-Blooded Orphans., Deadman Wonderland.

Edit: the Rurouni Kenshin OVA movie is nuts too. The old school one, not the 2021 version. Ninja Scroll is another good one.

Sounds like you'd also enjoy My Hero Academia, Monster, Mushoku Tensei, Hajime no Ippo, and Bleach.

Death Note & Attack on Titan

Older anime, but my all time favorite is “Fist of the North Star”, forefather of Dragon Ball Z, Jojo and many other animes

Steins;Gate

Shounen and its consequences have been a disaster for the Human race!

TRVE MEN ONLY ENJOY K-On! AND SIMILAR CGDCTS!

If you liked the Killua "game theory" arc against his own family in HxH I would highly suggest Promised Neverland. It's very good in that department.

I thought One Piece was a slog but powered through it and loved the later arcs, (although if you got past 483 and aren't hooked maybe it isn't meant for you).

Gurren Lagann

Ghost in the Shell: Stand Alone Complex

Assassination classroom, erased, cyberpunk edge runners, haikyuu, devilman crybaby, gurren lagann, a silent voice (movie), one punch man, mob psycho.

Lots of great options listed above. Castlevania on Netflix is also very good.

Afro Samurai, Sword of the Stranger are slept on

I would still recommend finishing Demon Slayer. Also, I started watching Mob Psycho and it’s p good imo

Based on the ones you mentioned—86 is really good. I feel like you’d also enjoy Mushoku Tensei since you watched Sword Art Online (also an isekai, but def a lot more fleshed out than the stereotypical low-budget isekais)

Mob Psycho - One of the best shonen’s out there. Great action, music, spectacular ending, and all around great vibe. Really grow to love the main character

My hero academia - others have mentioned, but very mainstream action anime so surprised you haven’t watched it yet. Watch the first 2 episodes and you’ll know whether you’ll like it or not.

Psycho Pass - Great darker seinen anime which has good action, subcharacters, and plot. Villain is also great which is a plus. The MC was very annoying in the first episode, but after you get through that, you’ll be hooked.

The Promised Neverland - Mystery with good characters all around. Only 13 episodes so easy to bang out in a weekend

One Punch Man - Unbelievably mainstream - even Bill Burr’s seen this one. Great action sequences and funny

Grand Blue - If you have a absolutely stupid sense of humor like I do, you’ll love this show. Reminded me of freshman year where my friends and I do would the most out of pocket stuff but we always had a great time doing it

Haikyuu - Good sports anime. Makes you really care about 7+ characters which is hard to do. Animation is good, opening music is some of the best out there, and it gets you pretty emotionally invested.

I don’t watch much anime anymore - this is a culmination of stuff I’ve watched over the last 10 years (and I have more recommendations lol) but I’ve found a good strategy to finding good anime is going on myanimelist.com and looking for stuff that has decent popularity and above an 8 rating. Found a good number of hidden gems doing that (banana fish is one good show I found doing this)

Ranking of Kings: It’s a pretty good shonen about a medieval prince who can’t talk. It’s a little more kid-friendly than I’d like but it might’ve just seemed like that because I watched it right after Evangelion. Only 23 episodes too so it’s a pretty quick watch.

I don't see DBZ on that list, so if you indeed haven't seen it, you should :) 

Other than that: Bleach, Code Geass, Berserk S1, Arcana (though not really an anime, it kicks so much a$$), One Punch Man is hilarious and creative, Evangelion is awesome too but don't expect much closure our of it...

I would suggest Overlord based on some of the ones you mentioned. I think it’s pretty timid/Americanized (like AoT/Death Note) compared to some more intense animes, and is pretty good.

If you haven't watched Neon Genesis Evangelion, I highly recommend it, but you will need to pay attention, so put the phone down when watching. You'll notice the last few episodes of the main series are very, VERY different (I heard they couldn't show the ending they planned due to Nerve gas attacks in Tokyo around the time this was made, and due to budget cuts they had to remake the ending and animation was rough... it will make sense when you watch it). Make sure you watch them to the end, things get very heavy. Once you are done that, you will need to watch the movie "End of Evangelion", it is basically the studio remaking the last episodes, due to massive pressure from the fans, (the story isn't changed), but you will get a better perspective, and is just a better presentation of the ending. 

Enjoy the greatest show ever made.

These are my top anime:

• Attack on Titan (9/10)
• Jojo's Bizzare Adventure (9/10)
• Demon Slayer (9/10)
• Your Lie in April (8/10)
• Jujutsu Kaisen (8/10)

Berserk, The memorial edition / 3 Golden Age Arc Movies (On Netflix)
Vampire Hunter D Bloodlust

I know some people call it a vanilla anime but I really liked Rurouni Kenshin
