Comparing the Glidden and the SW panels tonight, I would have to say that in general I see no noticeable difference between them. I still haven't taken the photos which will tell the real tale. Let me correct my previous statement and say I do see one difference -- the SW is hotspotting. No one else seems to have this issue, so I don't know what to think about it. The paint job (rolled onto BOC) is exceptionally smooth, much smoother than any of the other test panels or my RS-MM-LL screen. It's so smooth it's hotspotting. I think I need to try a different nap roller (used 3/16" I think) or even try spraying it. But otherwise, again, I can't tell a difference between it and the far cheaper Glidden. Both are a hair dimmer than the RS-MM-LL (with correspondingly darker blacks), but that's because the RS-MM-LL is hotspotting a bit too -- from any angle other than dead on, even just sliding over one seat on the sofa, the SW and Glidden are brighter than the RS-MM-LL.
