Pixel C or Acer Chromebook R13?

I'd been planning on buying an R13 to replace my Nexus 7, however, I've just ordered a Pixel C and keyboard for £370 as they're being discounted at present.

Anyone have experience of both/either of these?

Chromebooks seem to be Google's focus at the moment, so wondering if buying a Pixel would be a poor choice, but as they're the same price at the moment it was too good an offer to turn down. At least I have the 14 day return period if needed.
