For 2010 Fox doesn't offer the DHX 5.0, only the DHX RC4. It offer seperate HSC and LSC and has a bigger piston so more oil flows through those adjusters.
In 2009 the ROCO was comparable or better. For 2010 it looks like Fox took a step up.
However, with the travel of your bike and "mild downhill" and "5ft max" in your descriptions I'm not sure you'd push either of these enough to really tell a difference. They were designed for 8" travel bikes that see much faster chop and bigger hits.
My advice is to buy a Fox Float R, RP2, RP23, or RPL (plenty on Ebay for sub $100) and get it custom tuned by Push ($160). You'll be stoked with the feel on downhills, carry less weight, and spend less money than with these DH shocks.
For 2010 this is what Specialized is putting on the new Enduros.
