Hello,
I am not familiar with the Neolith product. We like the Plane product for many reasons, including the fact that it's available in up to 5' x 10' pieces. Regarding the polished vs. honed, we've had no issues using the polished in a variety of installations, including countertops (with scratching or staining). Per the Plane website, Plane has "features of engineered porcelain, including amazing flexibility, and is crack resistant, mold resistant, heat and frost proof, with no artificial binders and no VOC emissions".
I would advise discussing this further with your Plane provider to verify durability and what warranties they'll offer you.
Also, per my earlier comment on the product, I highly recommend that only an experienced and certified installer handle this product, especially in a countertop application.
Please let me know if I can be of any further assistance!
Micah
