There's a thread for favorite anime and now there's one for manga!
Tell us what are your favorite works and while at it, why not go into why you see them in so high regard?
I'll start off with my personal numero uno: Bakuman. I read it at a very unstable time for me, when I had no purpose whatsoever and couldn't make anything out of my life. But it was then that I happened to pick up this manga. It gave me hope when reading it, it was exciting to follow the main duo's path on becoming mangaka, as well as getting to know their professional input on the industry (since the authors of Bakuman were the ones behind Death Note). I also liked the creativity flowing throughout the entire manga all the while keeping it realistic and engaging. It resonated all too well with me and I'm thankful for it.
Anyway, other personal shout-outs going for Attack on Titan, Black Jack ni Yoroshiku, Medaka Box and Oyasumi Punpun.
How about yours?
