I want to lean more towards Rachel cause I loved her more even back in Ninja Gaiden Sigma 2, but she gets overwhelmed very easily against like 75% of the chars in DOA5U. So I tend to find more success with Momiji even though I'm really not that good with her yet. In the end, I love both chars equally cause they compliment each other's strengths and weaknesses and what one lacks, the other has.
