I gotta disagree. Surfer has operated above Thor's level in speed and vise versa in regards to strength. I guess if we do the math (IIRC someone said Surfer should be thousands of times faster than Thor or something of the sort) then you're right but then again, I never really gave a shit about stuff like that.
I'd like to point out that all the writers in question who have written their battles know that Surfer is extremely fast (One of them gave Surfer arguably his best speed feat ever) and have him for the most part giving it his best. Even while resorting to hit and run tactics he failed during Blood and Thunder.
Not really sure why it's so hard to believe that Thor has fast reflexes. True he has his low showings (Lower than most on this level) but his always hanged with boys on his level unless there was something that gave his opponents the edge. Call them outliers if you want (It'd be fair I guess) but he steps up when shit is on the line, he always has. Like I said earlier, there needs to be a caption describing Surfer as moving at x1242953950073^1000 light speed as Thor bashes him in the face, that will probably satisfy most.
