Genesis is always awesome, and with the addition of the genesis blocks replacing atomicblocks it's even better as they'll throw other blocks as well. I am using it with the Sample Theme and also with Navigation Pro and I am finding it very well, better than themes developed by third parties that work on snippets and that although are still on sale (like Mai Law and Mai Lifestyle themes), theirs developers themselves have already announced that they will no longer be updated as they too have started developing themes just like Gutemberg.
