please ignore the bandwagoners. New champs are automatically everyone's favourite until about a week later when they all get bored. My vote is Lulu because she's really versatile. She can support with her buff/debuff playstyle. She's a safe laner because of her cc and escapes, so she can build on-hit or even like an adc and do well solotop. AP ratios are not too good so she doesn't make for a good mid. She's pretty much ungankable though, so she can at least hold the lane.
