Well, you ended up with a KMC Z410 (sold as S1 in Europe) after all, so you're on the right track. Shame you got one made by KMC for a bunch of 'merkins who ride children's bikes :-)
Not sure how you can tell in less than a day that the cheapest KMC is better than a YBN (Yaban are a perfectly respectable chain maker, and Tainan neighbour of KMC), unless you just mean that a new chain is better than a knackered old one.
