Because there are so many different things that come to mind nowadays when one says "orc," I actually mostly avoid the term in my games. What are orcs, anyway? Are they Tolkien's goblins? Warcraft's cool green people? The "spectre, wight, or hell-devil" that haunted the Anglo-Saxons?
I use all three.
For the original, mythical orcne (demon-corpse) of Dark Ages mythology, I use the thoul stats and call them draugr (although elves will still refer to them as orcneas). These are the creepy-ass shadow-monsters that haunt the misty, boggy places where you'd expect Grendel to stalk off the moors in the dead of night, sneak into your mead-hall, eat all your thanes, and murder all your athelings. Not something a 1st level party wants to run into in the dark, let me tell you.
For Tolkien's yrch, I actually ditched the concept of goblinoids altogether and replaced them with Chaos-spawned beastmen. So my campaigns have ratlike humanoids called skavers instead of kobolds, doglike humanoids called mogrels in place of goblins, piglike humanoids called gruuchs in place of orcs, etc. They're all brutish, violent, disgusting, semi-intelligent (lacking tool-use or language and barely smarter than animals if there isn't a demon-prince or a Dark Lord around to drive them with its evil will and organize them into a Chaos army), and mostly just irredeemable little sacks of bonus XP.
For the Orsimer of videogameland, I make them one of my standard playable demihumans (they get their own character class!), but I term them ogres instead of orcs. (This is etymologically tenable: the Old English word orc almost certainly shares the same root as the Latinate word ogre, namely Latin Orcus.) This does require that I shuffle some monsters around a little bit: the 4+1 HD monster becomes a troll and the 6+3 HD monster becomes a greater troll. These ogres might be savages (noble or otherwise), soldiers, or city-folk, but they're always lean, green, and at least a little bit mean (in an endearing sort of way). They take more inspiration from Elder Scrolls than Warcraft, because… I don't care to play Warcraft, World of or otherwise.
