As the title states I'm running the above on their respective devices and can answer a variety of questions regarding it and can write about my experiences as well.
The iPad Mini started off a little worrisome... installed it and went to do split view where it immediately crashed and forced me to restore the device. After restoring it, all has gone smoothly and it works really well, even better than before on iOS 8.
iPhone 4S was rarely used on iOS 8 but after changing it to iOS 9 it's fast as stink. Loaded up every app and still no slowdown between switching and calling up new applications and such.
iPad 2 was really heavily used on iOS 8 and has seen an insane improvement in performance and lag and such, but after installing iOS 9 it has run like greased ****ing lightening. Absolutely unreal... Wouldn't believe it if I didn't see it myself
