I have just watched 200 different anime series

It took me 4 years.

I remember I started watching anime from October 17th 2016.

Do you mean 200 seasons or 200 and all seasons of each?
Give us your top 20 and state why?

200 AND all seasons of each.

It's very difficult to establish the top 20 best anime ever because there are so many that have left something special to me at the end of the show (it might be that I have felt a connection with some characters,maybe because of the plot or perhaps the graphics and drawings amazed me...).

But I can make a list (in random order) of all the anime that gave me something special (it could be a feeling or a reflection or just hype) at the end of the show.

The 20-30 yopu would recommend to others, then. Say why.

@AngryJellyfish, you have a rival in your midst

DEFO recommend classroom of the elite

Jellyfish doesnt need a rival, there are no impostors plus they are the person who has doen the most to promote anime on the site imo.
They like Baccano.

Seen that

you my friend have amazing taste
and yess i've seen so many animes. But same one piece has to be my fav, Oda is literally such a mastermind it love it. (also AOT is another big brain mby Isayama)
Idk if you've seen it but check out beastars. The 3d animation is a bit weird at first. but the show (and manga) are amazing

-Dr Stone:Any science lover will love it.
-Vinland Saga:Badass characters,interesting story and I love the fact that it's set in 1000 AD England.
-Steins;gate-Don't mess with a microwave (just jk😂)...It's a very interesting time travelling anime.
-Seinshun Buta Yarou:Best depressive romantic anime.And the main character is one of the best boi.
-Angel beats:It will give you depression.
-Your lie in april:It will give you depression
-Ano Hana:It will give you depression.
-Clannad:It will give you EVEN MORE depression.This anime taught me about living in a family.
-Assassination Classroom: I love many characters in this anime.
-GTO:The teacher (MC) in this anime is just awesome.I wish I could have a teacher like him.
-Attack on Titan:Classic Masterpiece.It covers many themes...the main one I would say is freedom.
-Naruto:It have an explosion of themes...war,love,hate,relationship,failure,success,hardwork,xenophobia,sacrifice...definitely worth it.
-Fullmetal alchemist:Brotherhood It have lots of interesting philosophical concepts to offer such principle of equal exchange,the basic of alchemy,the idea that everything is one and one is everything...
-Death Note:Really High IQ and very complex plot.Simply a masterpiece.
-Code Geass-It is very similar to death note.
-Kanata no Astra:It's about characters who are lost in the space.I love one scene in particular where I actually felt terror of being engulfed by the nothingness of the space.
-Magi:It's a little bit like fullmetal alchemist and code geass,so it covers many different interesting themes.Surely one of my favourites.
-Fate Seriesome fate series have nice openings (as many of the anime in this list),characters and I like the historical and mithological references.
-Konosuba:This anime is one of my favourite comedy genre along with also Grand Blue,
-The Promised Neverland:A very dark anime
-Made in Abyss:I started this anime thinking that it would be something childish...I ended up having trauma😂
-Gurrenn Lagann:WATCH IT IF YOU DIDN'T.JUST DO IT.
-Btooom:The best survival genre anime in my opinion.
-Erased:Another very nice timetravelling anime
