React Templates
For Gatsby
gatsby-starter-dimension
Very good looking. However, I think that it is quite limited in use. Good for showing off, but not much information to be shown. Unless I am wrong.

gatsby-starter-photon
This one is such good looking. However, I am not sure how easy it is to add blog functionality.

FlexiBlog
This is a paid Gatsby template for multi-purpose blog template. It looks good and seems to work great, with integration of useful technologies. These features might make the price worth it.
