Doesn't look worth it from that photo!

I am about to finally order our kitchen and wonder what the opinion is on 20 mm benchtop (engineered stone) or 30 mm. We are having Heritage Ezi Venice extrusion handles and I am a bit worried that maybe they will overpower the 20 mm benchtop? The cupboards are white and the benchtop is Grigio Mist (grey) and still deciding on a handle colour! Cheers and thanks :_

Is there a concrete like Laminate Kitchen Benchtop option available similar to the pic? Looked at getting caesarstone but our budget won't allow for it unfortunately.

We are doing the following to this kitchen: - Tiles replaced to large light grey concrete tiles (confirmed) - Cabinetry sprayed to white: sea fog OR half sea fog (note: walls are now half sea fog) - Benchtop replaced with white or grey stone Question: do we get white or grey for the bench based on the above?! options are: - grey stone (pictured with floor tile held against it) - plain white stone (not pictured but is plain white stone) - white marble with subtle pale grey marbling (pictured with floor tile held against it) white tiled splashback remains as is!
