I have gloss tiles in my laundry. They tend to scratch if someone walks a stone in and are extra slippery if water is spilt. It depends on how gloss you are talking about. Matt tiles can look a bit flat but they don't show dirt, dust as much. I just went with a semi gloss in my bathroom. The really matt ones all looked like outdoor tile to me. It would also depend on the colour. I am using black so very matt tiles looks too grey.

Perhaps you could post some photos of your selections? I am having trouble visualising what a blue marble-look floor tile actually is? Could you use it as a splashback tile?

Gloss finished laminate benchtops do wear and scratch faster than matt benchtops. Most manufacturers do not recommend that you use gloss laminate for horizontal surfaces for this reason. Laminex Industries have a range called "Diamond Gloss" which has a limited range of colours and patterns that they claim are suitable for horizontal surfaces. http://www.laminex.com.au/uploads/brochures/Laminex%20Diamond%20Gloss%20Brochure.pdf They look good in the photos, but they still feel like a laminate to the touch, and they don't fool anybody due to the dark edging. If your budget limits you to a laminate benchtop it is better to go with a solid colour in a matt, otherwise the imitation stone just looks fake and cheap.

Its going to stick out no matter what you do. Is there no budget to reface the cupboard doors and drawers? My Only Suggestion is to not do a White Gloss and instead use a Ravine laminate or a totally different colour and use the colour somewhere else in the kitchen like the off cuts for a frame for some artwork. Or on the kicks. If its going to stick out, and it will, then go all out. The next best option is go to a joinery company ask if you can take some off cuts out of the bin, make a temporary shelf and save up so you can do everything at the one time. If you redo the kitchen you will end up redoing that cabinet to get a consistent colour. Even with colour matching there is still slight differences because one is new and the other is old.
