Well that's true, but Guts also kills 100 people over the course of like 8 hours, which kind of tips the realism scale over a bit as well. I just figured he wanted anime swordfighting without lots of ridiculous extraneous stuff like magic, super speed, etc. etc. Champloo has really well-animated fights along that more "real" kind of vein, and IMO more entertaining than the ones in Berserk because the fights are longer and far better animated.
The Rurouni Kenshin OVA prequel series is also really good. Absolutely nothing like the Kenshin series. Although it's mostly Kenshin slaughtering people, there are still some really sick moves done and a nice duel or two at the end.
