I wonder if Metzu ever pulled the trigger on one of these after bombarding Pinside with comparison threads?
These are all decent games but put a little time on all of them and it's clear why they are "b-list." Lots of repetition, fairly shallow rules, show their age.
I'd just buy whichever one is in the best location at the best price. You'll get tired of whichever one you buy in 6 months and will sell it or trade it for something else.
