Beserk was decent from what I saw. The out-takes were pretty hilarious.
The original Hellsing anime was pretty fail in retrospect. Incognito had a lot of potential and was completely garbage by the end of the series.
Gurren Lagann is still pretty good. I definitely perfer it over the first Hellsing anime. To be fair, it's a very different type of anime from Hellsing/Berserk. I'd say it's the best in its genre.
