I haven't seen Trinity Blood because I hear that it's quite gory, but Rurouni Kenshin is by far the best manga ever to grace this planet, and dearest Kenshin is the coolest character to exist, right next to Uchiha Itachi from Naruto. I do wish the Japanese original hadn't chosen such a girlish voice for him though. A little deeper wouldn't have hurt. I think the character of Kenshin is one of the greatest and deepest characters. If you've read the final arc of the manga; the emotional pain..! I'm still very upset that the anime ending is full of fillers. Should've stuck with the manga.
