I've used both WLP002 and WLP007. I give WLP007 the big thumbs up and WLP002 the big thumbs down. I may have had a bad batch of 002, but attenuation was so slow that I thought fermentation had stopped after 2 weeks, with a high FG. However, after a month in the bottle, every one became a gusher. The yeast flocced well, but attenuated so slowly. It appears to need rousing.
The WLP007 however was fantastic. I've brewed a stout and an Irish Ale. The Irish Ale is a little ~too~ dry for my liking. I should have mashed at a higher temp. In any case, it surpassed 75% attenuation. 1.039 -> 1.009 for the Ale and 1.057 -> 1.014 for the Stout!
