Which is better Kayli or Kaylee?

My favorite spelling of this name is Kaylie. I love the name Kaylie for a girl. It's my favorite name. I think it's cute and modern. It's really pretty. I love girl names that end in -ie so that's why I like it spelled this way the best. There's nothing wrong with unique spelling though, as long as it's not too unique (ie. Emaleagh=Emily).
