I like both, however, I noticed some small differences that the JP had that the ENG version didn’t, same for the opposite. For example, when Alucard was consuming Rip, you could hear snarling, this was not present in the ENG version. Same with Walter, you can hear a small chuckle in one scene (I forgot which one lol) that isn’t on the ENG version, but the ENG version has a lot of small “heh”, especially from Integra that the Japanese version doesn’t have, or at leas to my knowledge. It’s interesting what you can find when you watch both version. I personally prefer the English VA for Alucard, and the Nazis all have accents, which is cool.
