Everybody comes with Surfer's great physical abilities and his speed.
SS's powers aren't really based on that. In other words that is just one of his many talents.
I admit that Kyle has shown his feats of energy "sucking". But the other side we don't know if Surfer could just disable the power of the OA ring. Maybe he can, maybe he can't. Current (well last seen) Silver Surfer was a pretty powerful boosted version. And last we saw Kyle as a Green Lantern he was a very powerful OA Soldier.
My points :
1. The ring can always react faster than we know. The stronger and more experienced the user is, the ring is a more powerful weapon.
2. Energy manipulation and cosmic power can be hurtful.
3. Kyle Rayner proofed that he can be an equal to any so called "big" cosmics or very strong warriors with wierd powers.
4. Green Lantern's powers (OA Power Ring) is based on will power and as far as I read Kyle's comics, Mr. Rayner's fantasy is pretty colorful. And better than that he is a very experienced Green Lantern
5. Silver Surfer is strong just people a little overrate his powers. When I came to KMC I saw a scan Wolverine stabbing Surfer.
6. We don't really know the limits of Kyle's will and the OA power...
7. That can be said for Silver Surfer. Except he got beaten a couple of times pretty bad by people with limited energy. (Warrior Madness Thor slapped him a coupler of times and if not for Beta Ray Bill SS would be...But that's another story)
That's all I can think of now.
