If you look closely in strong light, you will see that the MUFE has a slight blue undertone. I also found that this flaked on me. Bobbi Brown to me is like MAC's Black Black Chromaline (which I absolutely adore because it wears like iron) & both are a tar black color -- think asphalt. Many say the BB also wears extremely well. Check out the BB reviews on QVC.com. For the most true, purist black my #1 choice is Shu Uemura which also wears extremely well. My 2nd choice would be MAC's Blacktrack. The only one I haven't checked out yet that gets rave reviews is Clinique's. Whatever you do stay away from Tarte's Clay liner which completely dries in like a month. For an inexpensive drugstore brand, Wet 'n Wild to me is like Blacktrack -- slightly glossy. My HG's are Black Black Chromaline & Shu Uemura.
Just for the heck of it, you should check out MUFE new Aqualesse(sp.) liquid colors. Just saw it on the Sephora site today. It's a water- based pigment(?) that is safe to you anywhere on the body including the eyes -- technically is would be a liquid liner. On my way to Sephora tomorrow to check this new baby out. Note to self, check out the Clinique gel liner.
Let us know what you choose.
