They are all going to make great quilts. Sorry to tell you but the purple one is my favorite.
My wife and I also have a huge piece of your OBW fabric. I think we got it off a flat fold table at a discount fabric store. So far we have only used a bit of it for the back of one quilt, but we like it. This is our quilt:

I can't wait to see all these quilts finished, and especially the SAS! Then we get to see what you're starting next!
