I like intelligence, since no class gets enough skill points. In some cases, int will be more important than dex. If you want to be a powerhouse for dungeon or B&E stuff as well as social skills, then a high INT will very important.
High strength is useful for a more combat capable fighter/rogue. They can then use a greatsword and save a feat on finess. The character can then cause real damage on normal hits, and will have an advantage will sneak attacking. For example, a fighter 2 rogue 7 ( or a guy with martial weapon instead of weapon finess) using a greatsword deals 2d6 + 1.5*STR + 4d6 sneak. A straight rogue 9 deals 1d6 + STR + 5d6 damage. Assume the stats are either 20 DEX, 10 STR or 20 STR, 10 DEX. The fighter rogue deals 2d6+7 normally, about 4 times the damage of the 20 DEX guy. On a sneak attack, the 20 DEX guy deals 6d6, or 21 points. The high STR guy deals 6d6 +7, or 28 points. A 33% increase isn't bad.
Of course, the high STR guy has weaker DEX based skills.
It's possible to make very dangerous rogues by giving them fighter stats (high STR and CON). Although it negatively impacts skills, the strong and tough rogue is better in combat than "wimpy" rogues and still has much more versatility than a normal fighter.
Of course, I think the most dangerous rogue might have high INT and CHA, with relatively low DEX. They could steal power instead of picking pockets.
