A lot more guys is dangerous for anyone. But still, I've backstabbed someone with my dagger with someone 10ft away watching the whole thing and not even seeing me. He obviously sees the body and comes over to investigate, but it's more than enough time to sneak away and reposition myself. I usually go for the toughest guy and end him quick. If the others see me, no big deal. If they're too tough, I run away and prepare for the next backstab. Or if they are just reasonably difficult, I stay and fight to raise light armor, magic or whatever else I want.
And still, the key thing here is that a fight that would take you several minutes to complete with arrows, really does not take me any time at all with daggers. Bows are fun - I'm not going to dispute that point - but it's no where near as efficient as my dagger, and no where near as satisfying as stabbing some guy in the back and lifting him off the ground, jabbing my dagger into his shoulder, or cutting his throat. You will want to use what is more fun for you, but from a purely ownage standpoint, daggers is leaps and bounds ahead of a bow. Even if there is a x5 multiplier, that is still no where near a x30. Sneak is also not even a factor. Once you get it to a high level, there's no point in worrying about being detected. I'm already well on my way to being able to run around completely invisible to everyone around me. I can already stand in front of a lower level creature and they won't even see me. Bosses, or really tough creatures, are the -only- thing that can see me, and it's still really hard for them - I can still get off several dagger hits (if it even takes that many) before they are aware and notice me.
