Has anybody compared the two strains of Wyeast kolsch yeasts?

Which is the better

I've used the WY2565 and wasn't terribly impressed with the results. It fermented fine but I couldn't pick any of the Kolsch yeast traits that people talk about. Supposedly the WLP version is better.
WY2575 is a special release this year isn't it ?
