While I suppose my first anime was Pokemon, it's hard to consider the Americanized version as such. Was first introduced to real anime through the original Cartoon Network(RIP) with DBZ, Gundam Wing, etc in their afternoon block and quickly became addicted.
Soon Adult Swim broadened my horizon with Inuyasha, Case Closed, The Big O, Bleach, Cowboy Bebop (#1 rated by me), FLCL(top 5), Eureka Seven, Fullmetal Alchemist, Lupin the 3rd(favorit episodic), Naruto, Samurai Champloo, s-CRY-ed, Shin-chan, Trigun, Death Note, Wolf's Rain, YuYu Hakusho, Trinity Blood, and Witch Hunter Robin. Wow long list.
When I entered my 2nd year of college I was fully engulfed in finding new Anime to download and binge watch until 4 am, sleep and catch a sode before class. Now I have a subscription to Crunchyroll and keep up to date.
I mainly rate my Anime shows by how they make me feel through the first time watching so my list differs greatly from most I suppose.

Top 5 Long Anime: Because its hard to compare
There are plenty more left out simply because of the way it ended (SAO) or how it shouldn't have ended (Beyond the Boundary) (Highschool of the dead season 2?). I could go on forever but the bills wont pay themselves....
