I gotta say both have been fantastic for me. Both have had some hits and misses of course.
LOL has gotten a number of details for me, both work and love related. I know it was in another thread asking about if she gives bad news and yes she does. She is not afraid at all to tell you if something won't happen, or if it's going to not work out how you think.
Mystical is also really great too. I had a number of accurate predictions with her and she's never given me a fairy tale. I have noticed though with some things she says it sometimes doesnt always make sense until later on but she's generally very accurate.
