Adding another vote on the inovelli blues. Zigbee network has been rock solid for me. Integration with homeassistant has been flawless too - could not be happier with my purchase. It also helps that the company has a great track record with transparency and working with the community to improve their product.
One detail I don’t see mentioned often is the zigbee switches are a little smaller than the zwaves, making them easier to fit into the junction box. My house is old and has very small boxes - not sure these would have fit in some places if they were any bigger!!
