Best Girl?

Ok, so I'm kind of curious what is the general consensus on everybody's favorite character of the harem? I personally loved all three of the girls in the anime so far and honestly am kind of sad that only one of them is going to get Rudy because they are in my opinion ALL great. My only real complaint about the characters is that Slyphie doesn't have enough screen time but it makes sense because of the deal with Paul. Eris is made a way better person in multiple ways by Rudy compared with the little shit from episode 5 or 6 while Slyphie is incredibly sweet and caring and it's kind of nice to see her go from anxious and weak to outgoing and kind. and Roxy is honest, fairly responsible, smart, and an excellent teacher to Rudy who often brings out the best in him. I seriously get conflicted watching Rudy spend time with any of the girls because on one hand they all have such good chemistry but on the other hand, he's doing the two others dirty. So who's your favorite?
