The only thing I've ever saw in regards to IM's speed is that his computing speed works pretty fast.
Extremis is suppose to be one of his best armors

Which makes alot of sense cause he doesn't really dance around characters. He might able to tag someone agile like Spidey. But I'd equate that to locking on him in a way.
You might be able to make a case against New52 Aquaman though cause I don't see much in regards to speed. Hypersonic travel, should be faster than IM's Travel speed. In regards to reflexes alot of its generic laser/bullet dodging reacting.
