Marazzi has been hit and miss in terms of quality over the years. I tend to steer people away from their stuff, but some have used it. Most of the trouble I've has is with too much vairation in tile size, and with tiles being pringle potato chip shaped, slightly out of flat. Back to the "white line". I'm not familiar with the Marazzi "white line", is it right at the glaze/body demarkation? Grout won't "stain" the line, but it should cover it. It's just a matter of not wiping too much grout out of the joint when cleaning. Grout can wear over time, but it's really not that common in residential unless the installer messed up the grout and it ended up with less strength, then it could powder away over time. But again, no promises, as I haven't seen this white line for myself. My big concern is that if some tiles have the line and others don't, it's a problem of some sort. It might be a significant enough problem where it might show through the grout line, or at a cut edge. Inadequate glazing coverage? I don't know. The Villa Villeta that I've seen were pretty good tiles. DAL has several faux stones that are through-color, a few more that are glazed. I just put in an order for DAL Continental Slate, the Asian Black. A through-color. Not much "slate" color variation on the surface, just black/charcoal. Decent texture. It's a good tile.

@janine Hoffman I have RevWoos Premier in Cattail Pecan in my Kitchen, great room and office. I HATE THIS FLOOR there is something wrong with the finish or top layer it is impossible to clean and i have followed manufacturers care instructions to the letter. Brand new custom build and i was so looking forward to easy to maintain floors. I am devastated

Stephanie, Did you decide on a floor yet? I am in the same boat as you... Was leaning towards COREtec LVP, but am intrigued by the RevWood. I'm getting confused what will last the longest - LVP with WPC or SPC, or a laminate like RevWood. Too many choices! We plan to stay in our house forever and have pets. So we want something that will last decades, and will be installed throughout our whole house (except bathrooms). Looking to spend around $6 sq ft. Only requirement is that it is a floating floor (dont want to glue or nail down). This process is waaay more overwhelming that I ever thought it could be.

Turns out the boxes are labeled in that way: "Revwood", even if the actual product is Revwood Plus. There is an insert instead with "Revwood Plus" printed on it. Also, if you were using Mohawk MoistureGuard or SoundGuard or SilentGuard underlayments, the brand name shown on the label is "Performance Accessories". I have seen the blue colored one (MoistureGuard) is "Value Underlayment" and the white one (SilentGuard) is "Premium Underlayment". Confusing choice by Mohawk.
