If it where me, I would go for an oak worktop, it would look lovely with the cabinets and wall colour and then maybe a light creamy colour tile/ tile effect all the way through instead of the two different floorings :)

I'm a big fan of natural products so would definitely go for engineered planks, make sure the wear layer is no less than 3mm though. There is a misconception that laminate is more hard wearing than a timber veneer but laminate can chip and dent and can't be repaired. With a timber veneered engineered plank it can be sanded down and re-finished again and again. Try it with a tough polyurethane matt varnish to protect it further.

I think this is a pretty good article as I hadn't considered inspection points before. I normally wouldn't hesitate to have engineered wood in a kitchen however having got a puppy last year and completely underestimating the amount of mud she brings in Everywhere I would opt for vinyl. We don't have wood in our kitchen but solid and engineered elsewhere and I would also consider how slippery the surface can be particularly for a puppy who runs and jumps everywhere. I like LVT but i think they vary hugely even within the same brand as to how realistic they are so would shop around. Personally I also think LVT looks better with the design strips between the plank to mimic wood and I'd also speak to the fitter to see how it's finished around the perimeter of the room. My mum has a nice karndean floor but finished with clear sealant which I really don't like! I assume it's possible to remove the skirting boards and hide the ends of the planks as you would with wood to avoid this though? I think LVT is also a bit better re scratch marks (if you wanted to keep the wood looking pristine) and although it can still fade in the sunlight I don't think it will be anything like wood can fade https://www.woodandbeyond.com/blog/can-you-have-wood-floors-in-kitchens/

To be honest, if you are looking for the disadvantages of Dekton, is because deep down you sympathise more with Quartz. End of the day it all depends on which you like the most. As most the answer have said, if you hit the edges with something heavy the Dekton will chip. It is resistant to stain and to heat, which is the main reason people go for it. It means that you don't need to worry about heat or stains. It is a print on the surface, so yes the groves and edges won't have the veins, unless you have the Dekton drop-down mounted as a book, so continuing the veins. But the grooves would not have the veins. Quartz is pretty resistant to stain and you can request the extra treatment. In terms of heat, it is quite resistant but temperature shocks can make it crack. So cold to hot, or hot pot when the surface is cold. It is still a bit porous so I wouldn't push it too much with the stains. Good luck with your project!
