Has anyone tried DevkitPSP?

If so, how does it compare with the SDK for Ps2dev?
http://www.devkitpro.org/

looks interesting. But idk, this is the first time I've heard of it. I think that the official SDK is better. I am going to try this Devkit-PSP. DLing now.

EDIT: O.K. I downloaded it. It's basically a precompiled PSPSDK + toolchain + gcc. It's the exact same thing as xorloser.com's precompiled toolchain except this one supports automake/autoconf functions.

Cheers.
