Dell Powerstore arrays

Does anyone here have hands on experience with Powerstore arrays and would like to share their thoughts? They are fairly new; about 19 months of "prod" sells.

Physically, designs seem fairly similar Purestorage and HPE Nimble (Alletra 6000) NVME arrays. What I'm concerned with is how reliable they are, given how young the platform is. The feature list is impressive and competitive with the other platforms, but based on past experience with Dell, just because it offers a feature, doesn't mean it does it well.
