Out of all the different categories what do you look for in a manga?

My personal taste is an action adventure type with a romantic comedy story and I dont mind if its and ecchi as long as it dosnt compromise the integrity of the story line. I also like menga based on MMOs.


Some of the series I have read were:

1/2 prince (not finished they took it down before i could crying )
Air Gear (finished)
Death Note (finished)
Fairy Tail (in process)
Bleach (in process)
Naruto (dont plan on finishing)
.hack//sign (finished but gave up do to its hard to follow feels like im missing something each time i got a new episode)
Black cat (finished)
Negima (finished)
pandora harts (in process)
sword art online (in process)
freezing (finished)
accel world (in process)
hellsing (finished)
hellsing ultimate (havent started but I plant to)
Needless (finished)
elfen lied (finished)
full metal panic (finished)
evengelion (finished)
temptopa gurren laggon (finished)
Lucky Star (finished)

and more but this is all that come to mind atm.
