Here is a rogue build which tries to incorporate flexibility and utility without skimping out on combat ability. I built him as a halfling straight up rogue, no archetypes. He focuses on using daggers and fighting with two weapons, while taking advantage of his high dexterity. He has power attack/cornugon smash for debuffing capability and some extra damage. Considering he is a halfling he will hit more regularly than a medium sized race and has a healthy bonus to saves.
At early levels he has power attack to make sure his damage stays up there, and arcane spells like ghost sound and vanish for utility. Offensive defensive is a favourite rogue talent of mine as it allows a rogue to have a much higher ac than normal especially if you get all your sneak attacks off. I also gave him trap spotter so that you never have to tell your dm you are searching for traps and are always ready to find those nasty traps.
At higher levels I started with giving him a familiar (followed by improved familiar the next level for an imp) to give him a companion to use all his wands etc on the rogue to buff him, whether its haste, greater invisibility, fly, or simple things like glitter dust, an imp companion will help greatly the rogue, while also staying out of trouble with invisibility.
At level 12 I gave him dispelling strike so he can make all those magical buffs that enemy wizards cast on themselves disappear and at 14th lvl I gave him crippling strike to bring enemy strength down to 0 with sneak attacks.
Combat wise, if this rogue gets to sneak attack (a high chance considering his invisibility and ghost touch weapons) he does a serious amount of damage and is able to strip magical defences and generally bring a lot of utility to any party. I even gave him spell craft so that he could identify spells his enemies are casting and act appropriately, without having to rely on the party arcane caster to tell him what his enemies are casting.
He is playable without a team and is versatile and can stand on his own if need be. With agile weapons and his river rat trait, he does significant damage even without sneak attacks.
Meanwhile against anything he can sneak attack he will often outstrip the damage a fighter can dish out. His familiar gives him alertness and can aid him on most actions and is unbelievably useful in most combats. Given a couple cure wands he can even go around and act as a little healer.
This rogue will also hit regularly with roughly a 2x+31/+26/+21 at level 20 (easily hitting with him primary hits, and if he is invisible and/or flanking with his secondary/tertiary attacks too)
He has normal rogue weaknesses though and suffers when fighting someone with improved uncanny dodge or something that is immune to his sneak attacks (thankfully even in those cases he deals enough damage to be a threat and can always rely on his wands/scrolls to help in combat, something most fighters flat out cannot do).
