Ballpark challenge rating for this character? [Pathfinder]

[TwelvePointFivePercent]

So, I'm going to be running a superhero game in the somewhat near future, and I'm putting together some nice villains for the PCs to encounter.

One of the concepts (alright, several of them)is shamelessly lifted from a story called Worm. '1337' (as in "Elite") has a superpower that makes him hypercompetent, to the peak of nonpowered human skill, at anything he tries doing. So he's an olympic-level shooter, a master driver, computer wizard, master of every martial art out there etc.

The only limits is that he's restricted to standard human stuff. He can't throw cars around, teleport, or shoot lightning from his eyes.

Mechanically, that makes him level 6, with the class features of a 6th level Monk, Gunslinger and Rogue. He has average hp for his six d10 hd, 6 ranks in every non-supernatural skill as class skills, and, notably, knows every feat that he qualifies for which does not involve magic.
If a feat can be taken multiple times, he has it once if it stacks with itself, and once for each possible option if it does not.

Roughly how powerful would you say this guy is?

Statline, if it matters, is 15/18/14/8/16/13 (after dual talent +2dex/+2wis, +1dex from lvl)

ABP is in place, no magic items.

Same question, different character.

'Insight', is a 10th level sorcerer, but with wierd spells known. She knows every spell on the divination school of the sorcerer list, and no other spells, not even bloodline spells.

Stats:
Str 11, Dex 20, Con 13, Int 13, Wis 7, Cha 24 (including ABP and level bonuses)

Ballpark power level? Would you be scared shitless to face her as a 6th level group of people, or would it just be meh?

1337 I would eyeball at CR +1 for being gestalt martial and +1 for "all feats".

Insight could punch at her full CR by using Named Bullet and Quickened True Strike. -1 CR if she only uses one of them, CR 3 or 4 (total) she uses neither.
