I bought about ten spools of medium gray a few years ago and don't use anything else for piecing. I have bought hoards of it for quilting and it's pretty much the main thing I use for that as well. I'm just beginning to experiment with other threads though so I can't really compare it much to anything other than Coats and Clark. I really want to try Superior's King Tut thread because I hear it sews so well, but for the price I can get about ten spools from Connecting Threads! LoL*
