I think the others are all about equal, perhaps with mukm a little stronger, but all in the xx range, maybe barely into the xxx.
But oupz.com is a very neat one; very fun, pronounceable, easily-read, a clear standout and I think:
resellers = low to mid xxx at least
end users = probably high xxx or even into the low x,xxx if very interested.
Not as good as 'oops', but still a clear winner in the pronounceable LLLL game.
I'd hold on to that one for awhile; it ain't goin' to get any cheaper, and another year might really hike it up. Nice one.
