Sorry I missed this question! You have probably already made your decision.....but I'll answer anyway. I would ask a clarifying question first though. Are you vacillating between 2 undulating tiles, 1 matte and 1 glossy? Or a matte flat and an undulating glossy? II like both! It all depends on what else I have going on it the bathroom space. I might even mix them together! I almost always prefer an undulating tile over a flat one.....almost.
