I'm confused in how the general assumtion seems to be "If you are into Dragonball/Z and on the internet, you must therefore have experience with other anime/manga series". It's been this way at least since I first found DB-related internet communities in 2002, and given what I've learned of the history of the series and the internet since, probably before as well.
Really, the only anime I've seen has been on CN (and Nick JR back in the day, apparently.

), and I had a friend that showed me .hack//sign in Japanese my senior year of highschool.
So yeah, of the... maybe ten altogether anime I've seen, DB/Z wins. I was hooked on Detective Conan/CaseClosed from the first time I heard the FUNi intro at 4 in the morning... from a different room from the TV... but that kinda fell apart, since I immediately thereafter wound up at a residential highschool and the series stopped airing and *blargble*.
... FMA is cool, too. ^_^. And Sailor Moon, I s'ppose.
But yeah, other than Sailor Moon, DB is the only anime I've had a long-term exposure to, so I'd put it more with similar not-so-japanese shows I've seen lots of.
I don't know if DB/Z is the top of my all time list... but it has most certainly had a huge impact on my life, and I don't really frequent (or really even bother with...) communities for other series (Power Rangers and Sentai communities alike I can't get into. Either it's the horrible typing bleargh-fests, or the otaku explosia {*points to first paragraph of post*}... Doesn't do much for me.).
I will say though that for a couple - three or so years I followed a certain Starwars fansite... but I question whether it qualifies as a community, and I somehow failed to keep up with it after Episode 3 came out.
Ahem. So talking entertainment franchises in general? DB/Z is decidedly in the top ten. Top five or three, I should hope... but I don't like ranking and picking favorites and such, so nya.
