UEFI is well-supported now, for the most part. We have a good subforum at Kubuntu Forums dedicated to UEFI questions and answers. I've been spending a fair amount of time with UEFI on my ThinkPads T520 and X1; I've documented what I've learned. I'm also answering questions as they appear.

Some 3.8 and early 3.9 kernels have trouble configuring NVRAM variables for bootloaders, but I believe this has been patched in recent builds.

Secure Boot is probably OK to disable -- I'm not convinced it reduces risk for J. Random User, and I've disabled it on all my machines. But I don't advise people to switch to BIOS compatibility mode. UEFI is major advancement over BIOS and, once you learn it, you'll never go back.

Furthermore, I encourage UEFI users to switch away from GRUB and instead use rEFInd (1). This is an elegant boot manager that greatly simplifies dual-, triple-, nnn-booting. Each time you boot your computer, rEFInd scans all visible partitions for operating systems and displays them in a menu. Hardly any setup is required to achieve this, and you no longer need to worry about OS-specific boot managers. Don't install them at all.
