I am not a fan in any way with PAY. They did manage to raise something like $150M in capital if that boils down to just $5M it is still among the top3 stake coins and should maintain that base line. But this is crypto so UNO will likely over take XPY around $1.5M. so i can only hope.
Black I think has reach a stability point but has less vol. than UNO (hey everyone give yourself a pat on the back).
So it I think Black is one of the better pairings.
Quark has had a horrible record. And I have stayed away from it after getting burned by what I thought was a bottom midsummer 2014. But I gave it a second look and I think it may be a good move now. Fast, Mature distro, low inflation, safe network, fair market listings, and the kicker is a great mobi wallet. For that reason alone I like the idea of linking UNO to Quark since it can be the 'shopping' coin and UNO the investing/savings coin. (But Black and many others could play that role too).
Key idea being investors can move into UNO hold and then tradeout to a mobi/shopping coin to buy real stuff.
BTC absolutely sucks as a shopping coin (30min or more to make sufficient confirms whereas others can clear in under 2min or less).
If merchants use Coinbase, they don't have to wait 30 minutes. It's instantaneous with the backing of Coinbase. Coinbase will take care of any cheaters - after the fact. No worries for the merchant. Instant. Price posted, price received. Forget your worries, merchant. Accept bitcoin, no worries. ... WTF is Quark? Seriously, what the fuck is quark? Nobody fucking knows or cares or backs that shitcoin. UNO... Uno is an investment coin.
Reading all those comments above... listen people, you need to put things into perspective and ... simplify things... for example, does it answer an unsolved problem or is it a copycat of something that already exists?
Listen: Bitcoin is the first mover... Bitcoin has the network externalities. Bitcoin has the installed base and complementary goods... Bitcoin has the dominant design. Get it?
It's not going to be any of these other shitcoins in the long run... UNO offers long-term store of value... it's been proven over many months. These other coins have little to offer in the way of currency or store of value.
