I've never tried Fibre rich. I have tried Zoom Lash and Mascara X. I prefer Mascara X, but in my opinion, MAC's mascara's aren't as great as their other products. You should, however, get MAC's Prep and Prime Lash. Its a mascara base that makes your lashes longer, fuller, and helps mascara stay. You put it on before your mascara. Its the BEST!
