Is there an IKEA near you? In mine they put in several all white kitchens so it was easy to compare and contrast.

Not so many in mine ...

We did the old high gloss abstract kitchen with Pure White caesarstone and it looked great. We redid our kitchen in our new house using the ikea sektion high gloss cabs with semi handmade walnut cabs and this time did the pure white corian (or whatever it was called).

Well, remember that Ikea has hundreds, if not a thousand hands touching the counters every day.

I never found white (formica in my case) to be harder to clean or keep clean than my darker granite. I want the counter to be completely clean whether it is more visible or not. If I had white, maybe my other kitchen user would notice spills and wipe more thoroughly.

No I didn't find the quartz or the white corian hard to keep clean. We have a weekly housecleaner who gets out the spots. Otherwise, just regular cleaning. I do make some effort to not put super-staining items on the counter - like red wine or indian spices..., but even those ones will generally come out with a little soft scrub with bleach. I'm not sure if you're actually supposed to use the bleach products, but the guy who installed the quartz recommended it for me and I've used it (sparingly) ever since whenever I have a stain that just won't come out.

Ours aren't IKEA cabinets, but we do have white acrylic upper cabinets and textured laminate lowers, and used Organic White. We love it and it's been very very easy to care for (a spritz of Windex non-ammonia after dinner, and a wipe with a microfiber cloth. If there's every a spot the Windex won't get out, we use SoftScrub Gel).
