Welcome, Pat.
Well, that appears to be marketed as a porcelain tile if
this is what you're looking at.
I'd need our friend Mick to translate the Eye-tallian for me, but I can pick out "ANSI A137,1 impervious porcelain tiles" in there, but not much else.
As such, you will know a good deal about the general characteristics of tile, but you'll still need to know what the manufacturer claims as to the glaze and color and such properties. I don't see any of that on that site.
Same for the Daltile, but I don't even find reference to A137.1 on their site. Advertisement says it's porcelain, but without an ANSI reference we don't really know what that means.
My opinion; worth price charged.
