A good chunk of my z-wave hardware is from Zooz. I haven't tried any other brands, so I can't really compare or provide a solid "this is better" recommendation or anything. Mine are the older 700 series.

I've got a mix of the "Zooz ZEN71" for places where I need to switch larger loads (e.g., bathroom light and fan, all my outdoor lights) and the "Zooz ZEN72" elsewhere as it supports dimming.
