There are two sides to it.  On the zImage side, it's what the kernel
produces normally, without needing other tools, so it's vastly preferred
by the majority of kernel developers.  On the production side, uImages
provide useful things like a checksums and the ability to detect
overlaps.  If we enabled FIT images, we could go so far as to allow for
cryptographically signed images and configurations (what FIT calls a
kernel+fdt(+optional ramdisk)).

For community oriented things like this, zImage is best and for
production, it's up to the designer on what's important and what's not.
