Most of the complaints about quartz on these forums seem to involve MSI. Buyer beware!
I used a Pental quartz back in 2015 for a bathroom counter in my previous house. No issue with it for the 5 years that it was used by a teenage boy. Had an excellent fabricator.
In my new house I used quartz for the bathrooms/mudroom/laundry counters and they were sourced from Cambria (2 colors used on 6 counters) and Radianz (1 color used on 1 counter). No issues with any of those either. You want the best fabricator you can find.
I have used Cambria White Cliff in my previous master bath and my current one, and have been very happy with the brand and color.
