Either will work, but for a kitchen I'd choose the quartzite over the marble. (And I speak as someone who has an all marble bathroom with an onyx countertop so I'm not opposed to etching and staining either.)

Esthetically I think the marble goes perfect with your kitchen. I’d probably settle and choose the quartzite only because I couldn’t handle the etches and stains. Don’t get me wrong, I don’t mean settle as if it’s a bad choice. I just don’t like it as much in your space as the marble. Both are gorgeous stones.

I would go with the quartzite everytime. It's beautiful.

I think the marble goes with this kitchen better than the quartzite. The quartzite is beautiful but this kicthen screams MARBLE to me and it would be buttery in this space. The slab you have chosen is terrific! Good luck :)

Marble is nearly unsuitable to be a kitchen countertop for what people expect these days. Think about the color years from now, not just today. How's that big blue Kool-Aid stain in your marble gonna go with anything?

Do people really drink blue Kool-Aid?? Yikes.

You could always go for a quartz that looks like marble if you want more of that look.

i am a fabricator. Quartzite. I've had too many customers that regretted marble in their kitchen.

Marble is beautiful. Get something else. As you know, it stains, etches, ...

And there's a reason paint should be picked last. Consider that going forward, for the kitchen or any other work you have remaining.

There are so many awesome stones out there to choose from, I had a hard time with it when I was deciding. I loved so many of them. I did finally decide on marble because I couldn't find anything that really gave me that organic feel I was looking for quite like it. I don't regret my decision at all, I ADORE IT. I am not remotely careful with mine (and yes there is some etching, but I have no staining). My fabricator referred to marble like a good pair of jeans, the more wear and tear, the better it gets. Don't let people who couldn't live with it talk you out of it - if you really do love it, and are informed about what it's characteristics are - go for it! It's yummy :)

Choose quartzite over marble. Both look great, but quartzite is much, much easier to maintain than marble. We wrote about Super White Quartzite because people were confused and weren't sure what kind of stone is it. Quartzite is a natural stone and depending on a slab you find, it will resemble of marble quite a lot but it will be easier for you to maintain it.

"Marble will stain from anything acidic,..."

In the quote above from your article, you meant to use "etch" where you used the word "stain". While I suppose it's possible for an etch to simultaneously cause a stain, the two are usually distinct.

Quartzite doesn't etch. If a "quartzite" etches, it is mislabeled and is really marble. (This happens a lot with super white which is usually mislabeled quartzite but is usually really dolomite marble.). Check out the countertop geology threads here where a geologist explains how to test slabs so you know whether you are getting marble or quartzite.

You can seal marble to prevent stains, but you will still have etching. (I think there are some expensive processes now that claim to prevent etching, but I don't know if they really work and I remember people here who had seen them saying those resulted in the marble looking plastic). We had honed marble in our last house and I loved it, but it was an old house and I love antiques and patina. It is not for everyone.

If you like the quartzite and it is really quartzite and you can afford it, I would go with that. It's hard to see colors correctly on screens so we can't really help much with whether the quartzite looks good with your other colors.

Does etch-proof marble with Stoneguard look like plastic to you?

Haven't see it in person and have no opinion. I would just suggest that anyone who is interested search for threads here to see opinions from people who have seen it in person and/or see a sample before committing. Since you have seen it in person, maybe you'd like to offer your opinion.

Having seen women nearly in tears over their countertop choice made based on lies from their fabricator, I look for alternatives to replacement that may dry their tears. It isn't for everyone, but for some it's a cost effective solution.

I would pick the quartz.
