The thing about WY1007 is that it tends to take longer to ferment and clear than, say, WY1056 (or WLP001). Makes a decent IPA, but I wouldn't say it makes a "better" IPA than an American Strain. I'm in the opposite position. I would love to use WY1007 for my alt in my brewery but I'm hesitant to switch from WLP001 for my IPA because of the turn around time on WY1007. I can get WLP001 to clear up much faster and it makes a pretty darn good Alt, so thats what I use for now (and I don't want to have to deal with another "similar" strain.)
