okay, I was in a bit of a hurry (sharing a bathroom with 4 people sucks big time) so they're not the best, but you can still see the subtle differences, imo:
L'Oreal Voluminous (waterproof)

^You can tell it creates a thicker lash by looking at the lash roots, but some minor clumping problems occurred.

Max Factor Volume Couture (waterproof)

^a longer, more defined lash

Max Factor 2000 Calorie (waterproof)

^to me it's the best of both worlds. Longer, thicker, more defined with less clumps

Each picture has two coats of mascara, without the use of a lash comb. HTH!
