Harmony Rose gets a slight edge for being a bit sluttier and all natural. If Tory Lane had her original chest, I might go with her. Isn't there a both option? I am pretty sure that they are long time friends and have appeared in a bunch of scenes together
Tory lane's got a bit of a weird voice when she's at it, she can sound like a dog with something stuck in her throat. Purely on that basis, I go Harmony although the volume can be turned off. Volume off it's too close to call.
