I'd argue Ben Grimm's probably got a high SPD, probably middling dex, because it's all skill for him. An 18 dex, SPD 6 or so, 4-5 levels of HTH, boxing, and a few HTH damage classes would probably cover it. I say this, because he has demonstrated repeatedly that he is an extremely skilled fighter, capable of trashing entire armies of goons, punching above his strength class, and massively outclassing the guys that are in his weight class, through sheer skill.

Having watched people for a great deal of my life, I disagree wholeheartedly on heroes not demonstrating exceptional agility. Name an Avenger or member of the Justice League who is not exceptionally agile. Those who lack considerable agility aren't common and the ones that do exist often don't last long. Among the Avengers, the only two I can think of that really don't have exceptional agility are Doctor Druid and Scarlet Witch, neither of whom need agility to be effective heroes. On the Justice League the only one I can think of is Swamp Thing, once more, a character that doesn't need exceptional agility, because their power set doesn't need them to be anything like nimble.
 
Now, the X-Men, those guys tend to be a fair amount slower, except for the main team, probably because most of them are not exceptionally well-trained or suited for combat, but even the main team is nothing compared to dex monsters like Spider-Man, and he is a monster in combat.
 

The short and sweet of it is that Pathfinder is a D20 game. 
 
As crunchy as HERO can be, most of your abilities can be summed up in a character sheet (barring some rules) and it's technically got easier math, but you're going to be doing a lot more of it, because there's little bonuses everywhere. In Pathfinder, you get no such luck, every ability has a paragraph or blurb. It's also less balanced as a result of these things and subtle changes in words can differentiate between something astoundingly powerful and something astoundingly weak. There's also the issue of rules interpretation. For example, there's an ability the paladin gets that describes 'a weapon' now, is this one specific weapon, or one weapon on their person? It's not clear and it's not covered in FAQ or any form of errata.
 
If you limit yourself to just the main rulebook, you'll find that the Monk is basically useless, unless you really want to be a kung fu master. Though, in truth, a dedicated 'boxer' fighter is nearly as capable. Plus, there's a lot of fun to be had in the other books, just don't expect it to be balanced. The Wizard in particular has some stuff that can wreck about anyone at level 1.
