Advice on thief

Getting ready to start a new runthrough and want to thoroughly try out the 3rd edition sneak attack option. So this character would definitely be in melee regularly operating as more of a combat rogue. What do you think would be better at this role:

Half-Orc dual wielding fighter/thief

or

Half-Orc single wielding pure assassin

or maybe even a

Elven Stalker dual wielding longswords


I'm open to another races. These are just the ones that sounded cool and seemed effective.
