I'm throwing the Best WCP1306SS into the mix. I ordered the XO, but it arrived with almost no packing. It was just loose in the box with a few pieces of cardboard. The stainless wrap was pulled back, it was dusty, had fingerprints and was missing the template and mounting hardware. Contacted support as it had obviously been returned and it would be 6 weeks to get another.

The Best is only 22" deep, but everything else looks good. From what I gather, they are also super easy to install. I doubt anyone knows much about them, but figured I'd post and see.

Best isn't an unknown brand. It's most unique product is its Cattura downdraft hood that can be installed in a variety of ways including behind a range rather than only behind a cooktop.
