Eldritch scoundrels don't necessarily have to be far behind in sneak attack. With accomplished sneak attacker at level 7 you're 1d6 behind, and it doesn't get worse for another 4 levels. On the plus side, you get to vanish as a swift action, almost ensuring sneak attack every round. Sure you lose a few skills, but you also gain 6 level casting instead. Overall, it's a really good rogue archetype, probably not as good as a full arcane caster, and requires you to play a little different than a normal rogue, but still a really good option.
Sense Vitals also adds enough to make up for the difference, and is a 2nd level Wizard spell. Add in Accomplished Sneak Attacker you can actually have more Sneak Attack than a standard Rogue at higher levels.
