Silver Surfer vs Orion :Payback!
Round Two, the first time he jobbed so hard to Surfer he may as well call himself Champion.
Bad crossover aside, I won't say Orion can beat Surfer the majority, but I can't say Surfer would either.
Orion (well written) is powerful enough to hang with Surfer and score a few wins.
Remember, they both have planet destroying powers, and they both have universal powers.
The Astro-Force was once used to counter and stop a universe destroying blast.
Surfer may have him in the speed depo, but not so much in space, Orion has flown to other planets in minutes, he also has godlike reflexes that allow him to counter and attack others who can go lightspeed.
Now, add that to the fact he can put up a shield strong enough to take an Omega beam from Darkseid, back when DS was immensly powerful, and he also has a healing factor on par with Hulk and strength on par with Superman, and skill on par with Thor and durability on par with Thor.
Also, Surfer is indeed weak against magical attacks, and that's basically what the Astro Force is.
(If we want to go by cross overs, the Astro force would have the same effect on Surfer as the Omega Blasts did.)
I believe Orion can definatly hang with the likes of Surfer, he is far far underrated.
