well just from these two shadows i would say YES as good as or maybe better but again, it could be the two colors i've chosen and how great they are. i don't know if there's anything in mac like bitten, probably so but i couldn't find it and the cocoa bear is like brown script but a tad better as i commented above.
i did notice that while the eyeshadows do fit in the pro palette perfectly there isn't a little magnet like the mac shadows have. not an issue if your palettes are mostly flat, like mine but if you travel or hold your palettes up for videos etc, they'll fall out. no biggie for me.
i totally think her stuff is worth a try. i'm sort of on a self imposed makeup buying period until after the new year but i might go out there and make a list for later
