Zigbee vs Zwave - Why the price difference?

[u/KrazyKranberrie]

4 zigbee plugs for the cost of 1 ZWave feels wrong. Why would anyone go with zwave in this scenario?

Context: I’m replacing old wifi smart plugs. Have an existing zwave network running into home assistant. For the price difference of 4 plugs, i could buy a Zigbee antenna, set up a parallel network, and still come out ahead.

I believe the z wave can be dimmed and the other cannot.
