The Ellie/Lisa comp is a good one. Similar limitations (Ellie a little more permissive in some respects, Lisa in others). Lisa a little prettier, Ellie definitely has the better bod (and I've got zero complaints with Lisa's bod!). Both speak English relatively well, very friendly and very service oriented.
Right now, I've got Lisa ahead, feel like I just have a more authentic connection with her (i.e., she's a more convincing actress lol).
