What's the best quality and cost effective smart plug for on/off and power usage monitoring?

I read about INSPELNING but I'm curious if there are other options folks here can recommend before I pull the trigger?
I have zwave and zigbee but I think I would prefer zigbee.

Looking for advice about a device to buy? Remember to provide guidance on:

• Which country you're in
• What your budget is
• What protocols you prefer (eg Zigbee, WiFi, Z-Wave)
• Any features you want (such as power monitoring, dimming, etc)
