Your favorite Anime Studios/Producer?

Ufotable,Mad House, Ghibli Studio,Toei Animation and CoMix Wave Films

My favorite anime studios are J.C. Staff; Bones; Brain's Base; Studio Chizu; Trigger and Studio Ghibli.

MADHOUSE >>>
there are many other good or better studios, but I prefer Madhouse

Madhouse, Bones, Studios Pierrot, A-1 and David Productions. Especially Madhouse, they seem to be the converging axis of quality and quantity. They have made a ton of titles I've rated very highly.

Studio Ghibli.

Only this one in my favourite list for life.

This is a old question for anime enthusiast.
What studio produces productions that you consider to be fantastic and love the style of their output?

As for me, i'm a big fan of:

J.C Staff - One of my fav anime Studios/Producer. They are simply amazing.
They produces amazing Animes and doesn't left behind in the original story.

For me its White Fox, they really been doing awesome ones, Sunrise are good too

Madhouse, ufotable, and Bones for sure. Although, hearing about the overworked production assistant at Madhouse that collapsed and was hospitalized due to overwork was pretty disheartening.
