I'm a big fan of Zooz switches. I get that folks say Lutron switches are "bullet proof" but I've only ever had an issue with a single Zooz switch and it was replaced in two days by Zooz.
The Lutron devices also don't contribute to building a robust Z network. So, now you're in the realm of spending double on the switches, plus having to supplement whichever flavor of Z network you prefer with other mains powered devices to serve as repeaters (this may not be an issue if that's already part of the plan anyhow).
Price is the largest issue. $59 vs $29 for a basic on/off switch. Add that up to the scale of a full house and the difference is significant.
