You can be wearing Heavy Armor, with only 1/5 in Stealth & Muffled Movement & can kill several enemies with a Bound bow while sneaking, before the can figure out where the shots are coming from. You can be wearing Heavy Armor, with 2/5 Stealth, and all perks up to and including Silent Roll and do a roll Sneak attack with a strong enough dagger killing without alerting anyone even if they are standing right next to them. A weapons weight affects noise and detection more than armor does, if you have muffled movement. Because of that Bound Bow's weight of 0 will always make it the stealthiest bow.

On a side note, it also helps when killing enemies in dark areas, since the arrows glow.
