I plan on installing Debian 6 on my server build with a E3-1270, 16GB DDR3, and 2x120GB SATA3 SSDs. But this has me wondering, should I use Intel's built-in, on-board software RAID or the OSs'? Which will perform more efficiently? Which is simpler? Please give me a solid answer. Thanks!

OS-based software RAID is more portable in the event of a hardware failure. Use that over motherboard-based fakeRAID. all things equal, use mdadm or ZFS over the motherboard.

Hardware RAID > Software RAID > fake RAID.
(Honestly, I prefer no RAID above fake RAID, but that's probably a matter of personal preference.)

They both work the same way. The only difference is who keeps the container information.

I would suggest to find an Hardware RAID setup which is optimized for use with SSDs. AFAIK most SSD are RAID similar setups internal (connecting the modules in the frame and providing caching), which might perform slow on 'normal' (hardware or software) RAID controllers. Most (cheap) SSDs carry a JMicron controller, so perhaps you should focus on a decent hardware RAID controller for JMicron SSD devices, to improve life expectancy and read/write speed/caching on the RAID setup.
Unfortunately i've never reasearched this myself, but i know special SSD RAID setups exist..
