Yeah, she may actually be a more fluid player but her guitar tone ( often generic in videos I've watched ) is not as good and neither is her voice.
This JST girl is going to really be something in a few years. Shes got the voice and the guitar tone. She's a little stiff sometimes ( in other videos I've watched ) but shes much better overall imo.
The Chantelle girl seems very comfortable playing but she also doesn't seem to have a handle on tone/emotion ( which is kinda what it's all about ).
I'm sure some of each of their talents get lost in the videos but that's what I hear.
