In order of air time starting Mondays (US time because 'Murica).
Vinland Saga - AKA, slaves on a farm. So the first season was Thorfinn forced into battle, now he's gotta learn other skills from his bro Einar. Probably won't be long till the bloodshed starts up again.
Ayakashi Triangle - Gender bent exorcist ninja fighting ayakashi and being one of the girls. May want to wait until the physical release for the true uncensored version. Is this even still part of this season with the delays? Dunno.
Eiyuuou, Bu wo Kiwameru Tame Tenseisu - Boomer king gets reincarnated as a cute OP girl and finally gets to live life for herself as opposed to worrying about a kingdom. Plenty of time for combat and becoming even more powerful!
Ningen Fushin - 4 adventurers suffer horrible betrayal and lose all faith in humanity, and decide that since they still need to eat and pay for their hobbies they may as well work together.
Tensei Oujo to Tensai Reijou no Mahou Kakumei - Yuri featuring a "mad" scientist princess and a noble mage? Sign me up!
Bungou Stray Dogs - Skip if you haven't seen the previous seasons, or rather go back and watch them, cause this one's been solid all the way through. Otherwise enjoy the story of a detective agency full of "gifted" people with superpowers based on famous authors fighting in increasingly over the top battles of both brain and brawn. Also they have the best healer ever, who has to kill you to revive you at full health.
Tomo-chan wa Onnanoko! - Great comedy about a tomboy trying to get her childhood friend to see her as a girl. Lots of good characters in this one, I bet you've seen the memes by now.
DanMachi - Only complaint is not enough Hestia this season, but the highest stakes yet! Fighting against an unbeatable avatar of destruction and ending up falling into the dungeon's deepest levels while severely wounded, how will our heroes make it out of this one?
Oniichan wa Oshimai! - Very cute and funny, and probably the best animated show this season. Slice of life about a NEET adapting to "his" new life as a middle school girl thanks to his sister's experiments. Triggers all the right people too as an added bonus!
Nier Automata - Probably not going to get much out of it if you already played the game, but if you didn't it's a good explanation of the story.
Rougo ni Sonaete Isekai de 8-manmai no Kinka wo Tamemasu - An isekai where the MC didn't die, AND can go back to her own world! Having gained the power to do so, she opts to open a shop and bring current year items into a medieval fantasy world in an effort to save enough money for an easy retirement.
Benriya Saitou-san, Isekai ni Iku - Jack of all trades handyman gets isekaid right BEFORE being hit by Truck-kun. Now he's part of an adventuring party effectively serving the role of the party thief and also remembering the wizard's spells. Gets surprisingly dark and deep as it goes on.
Kyokou Suiri (In/Spectre) - Yay Kotoko is back! This is the one I was looking forward to most this season, and haven't been disappointed yet. If you watched the first season you know roughly what to expect. Our heroes go out solving problems between the spirit and human realms before they get out of hand, which they probably will with Rikka still being on the run...
Mou Ippon! - Finally, the sleeper hit of the season (for me anyway). I was on the fence about this one, almost didn't watch it. But I'm glad I did. Cute girls doing (very well animated) judo, going to the hotsprings, slapping dat ass, etc. If you watched any other sports anime you know about what to expect from the story. The characters make this one a cut above.
