Is Feline Kohl Power Comparable to UD's 24/7 Liner Zero?

[vocaltest]

I LOVE LOVE LOVE Feline Kohl Power. I can imagine me using this up so quickly and I really want to get a backup. Its on the goodbyes section of the UK site BUT... I have no money whatsoever, and I'm worried that it'll be gone when I get paid

! So incase it does go by then, does anyone have both of these liners? Are they comparable in colour, intensity, and staying power? I only use Feline on my waterline as its the darkest eyeliner i've ever used and it stays on forever!
TIA

I MUCH prefer the UD pencil as it doesn't smudge on me like Feline does. It isn't as black as Feline but it sure stays on better. I really like Stila's convertible eye color pencil in onyx. It is really black like Feline but it doesn't go everywhere like Feline does...it's like best of both worlds!!!

I also prefer UD's pencil!
I do love Feline because it's very black but, I smudges like crazy. I end up using Ud's way more.

I'm three for UD Zero. I have both and they are great but Zero lasts a lot longer and doesn't smudge like Feline.
