Well the display of the Z is ridiculously sharp than a Super AMOLED. But brightness, Vividness and deeper blacks will always go to the Super AMOLED.
Viewing the Z at normal viewing angle makes it really really good on the eyes. But the Z is abit warmer and there's no option to change it like the ones from Samsung Galaxies. Good thing there's a way to install the White Balance setting found on the ZL to the Z. And like me who prefer displays abit cooler, that's a godsend specially when viewing white webpages like neogaf mobile.
As for the Camera, I'd rate it 7/10 (8/10 for the Note 2). it's much slower than the samsung, it takes about 2-3 secs to open the app from the launcher, and 1-2secs to open it from the lockscreen. Capturing shots is also abit slow since the Z refocuses when taking the next shot. Burst shot solves this but Superior Auto and Normal shouldn't refocuses especially when the focus mode selected is touch. Also photos taken from burst shots are taken to subfolders per batch. It sucks in viewing from the camera gallery.
My Z is now rooted and running a custom rom (but the bootloader is still locked because of my shitty windows 8 drivers) that enables me to install a mod to make the status and softkey's bg black instead of grey.
