Hated Eva.
Sorry, had to say it.
As for stuff I like...
Lodoss OVA, 08th MS Team, Gundam 0080 (another UC fan), Nadesico, Cowboy Bebop, Vandread, Big O, BGC OVA
Those ones head out my list.
Regarding Adult Swim - the AS edit of Cowboy Bebop kept most of the stuff that would have been cut from the Toonami block, although I hear a few things were still removed (already had it all on DVD, so I didn't bother to tape it - they also didn't show a few episodes on the first run - reasons for that included shooting someone who looked like a little boy, an episode with a hijacking, and a bomber who blows up buildings that look similar to the WTC - the initial run was right after the WTC, and the missing episodes aired on the second run). One thing to note, however, is that not everything currently airing on AS is edited for the AS format. The people in charge of AS recently had the option to expand it, but they had to find things to fill the new time slots right away (or they'd lose the time slots). As a result, two of the shows - Yu Yu Hakeshu and Pilot Candidate (originally Candidate for Goddess) - are being shown with edits that were made with the Toonami block in mind.
