What has better IQ for indoor flash free, XZ-1 or XZ-10?

Based on the few samples from the xz-10 I've seen I'd say the XZ-1.

The xz-1 you need to shoot in raw though unless you can avoid subjects including fur, hair, grass or foliage. It's decent at iso100 but not good. At all higher sensitivities the noise reduction makes everything look like cheep plastics.
