How is the Google Nest better at connecting with Alexa than the Ecobee 4 that features built-in Alexa voice services?

I just got the Emerson Sensi Touch thermostat but for the life of me I just can't find the usage report! I checked the manual, I checked every options under the settings menu. I want to see how much energy I'm using and see whether the kids are playing around with the thermostat (even though I always tell them not to!)

I don't have a ''C'' wire, whatever that is. Can I still install the Ecobee thermostat? What else will I need to install it, do I need to go down to the hardware store?

Are all of these Alexa compatible? Do I only need to use the thermostat for Alexa or not?
