It doesn't matter how solid or not 7.1.2 is in itself because iOS 8 is more refined and refreshing in UI no matter what.
The difference between 7.0 and 7.1 was huge and going backward was impossible because it was a downgrade in experience. 7.0 just felt worse.
Going back to 7.1.2 from the iOS 8 beta also makes me feel like my phone is less solid.
And 7.1.2 is even worse on iPad with messed up multitasking, rotation screwing with the pages, dynamic wallpapers being cut off, App Store locking up, and other problems that weren't fixed in 7.1.
