Any manga worth my time reading?

You should read "LIFE". It's a shōjo series created by Keiko Suenobu. I've only read one volume, but it's really good. (If you read it and like it, I'd appreciate it if you joined the Fanpop club I made dedicated to the series. It's called "Life (manga) ライフ".) You can read it on MangaFox.
Anyway, here is a basic summary of what the manga's about...
Ayumu Shiiba is studying for the all-important high school entrance exams. She is struggling to get by, but thankfully has help from her best friend Shii-chan, who is at the top of their class. Test results come back and their friendship falls apart when Ayumu surpasses Shii-chan's scores and gets into her high school of choice while Shii-chan doesn't!
Losing Shii-chan is so painful for Ayumu that she starts cutting her wrists for comfort. Hoping for a fresh start, Ayumu arrives at her new high school and finally opens up to a new friend, Manami. But will Manami prove to be the friend that Ayumu truly needs or send her further in a downward spiral?

Taste in art is completely subjective. While I'm aware of all of these series, I have read none of them. 07: Ghost is on my queue though, but only because it's a Zero Sum publication.

Naruto borrows heavily from Hunter x Hunter, which is arguably better. People who like both series say "at least HxH doesn't have all the filler that Naruto had."

Mahou Sensei Negima is notorious for starting off as a herem series & completely transforming into an action adventure series. If you liked that part, Majin Tantei Nougami Neuro does the same thing, except the first half is a mystery/comedy & the second half is horror.

Well, none of these seem to be old mangas. Fruits Basket is from the 90s, so it's the closest thing to a classic. I did see the anime to that...Reverse Harem genre..... You might try Angelique, Neo angelique, or Ouran High School Host Club.

Fairytail!

"ID" is a good action story with a plot. The first couple volumes have TERRIBLE artwork but it quickly gets better and more beautiful. It also has a great plotline. Based on what you like, I would suggest giving it a shot.

It's not really a Manga..it's an online Manhwa in colour.

The Genres are: Action, Comedy, Drama, Mystery, School Life, Sci-fi, Shounen, Supernatural

The Story is really good, it has sad, funny and exciting Moments.

And you just have to love the main Characters! xD

At the Beginning the art might not look that good (but already pretty good xD)
but it get's awesome after a while! x3

Urm...Kuroko no Basuke manga and Dorohedoro.

There is an anime about Kuroko no Basuke and it is ☆awesome☆ but you can read the manga which is as equally ♡good♡. The drawing style at first is pretty comical but it gets really good as the story progresses.

Dorohedoro is an EXTREMELY WELL DONE manga and it is horror. Yes but it's not that scary. In fact, it's a touch on romance, adventure, mystery, slice of life and comedy. Highly recommended for this manga and the drawing style is a bit particular. Not that nice for people who read a lot of shojo but since you read old manga so tgis should be ♢marvelous♢for you! ♡ It also has good story plot! Beware of long chapters though if you're reading online.
Summary: ( from Baka-Updates )
The story revolves around Kaiman, who does not remember who he was before he was transfigured by a Magic user. This transformation left him with a reptile's head, and a desire to find out the truth about who he really is. Accompanied by Nikaido, his female companion, he tracks down Magic Users in "The Hole" and unceremoniously chomps down on their head, hoping to find out who it was that put him in this state. One by one, they witness this "second man" inside the head of Kaiman, and after pulling them back out of his mouth he asks them all a question...

"What did the guy inside my head say?"

Strider Hiryu
It has 6 chapters(Plus a prequel story)

You should try The World God Only Knows and Beelzebub.
