I'm not sure it's fair to compare Bleach & Inu Yasha along side Cowboy Bebop and Outlaw Star since there is a huge difference in the size of each series. The first 60 some-odd episodes of Bleach are great but as the show wears on and as all the filler begins to irritate, opinions drop.
I went with Outlaw Star because that was the only one where I really wanted more adventures with the crew.
@xybernauts: I believe a follow up series called Inu Yasha The Final Act concluded the series. 26 more episodes on top of the original 167.
