I don't really like either, but (anecdotally) I've found the Google Home experience to be nicer. I fully intend to get rid of all my current "smart home" trappings when I move, but I have a hard time denying that Google has come in clutch a number of times. Alexa is
fine, but there's sorta an inescapable air of consumerism that surrounds using it. It's like you're fighting against Amazon to get the functionality you want most of the time, which is more annoying than it is helpful.
Look on the bright side, at least nobody bought you a Homepod!
