Garage door opener installation - hardwired vs. outlet power?
Personally, I'd prefer my garage door opener to be outlet powered so that I can unplug the thing when I need to do something with it, instead of going to find a breaker. Other than ease of disabling, I don't think there is any compelling operational reason to do one or the other.

Of course, if your next opener can't be hardwired, that might be a reason to not hardwire this one (the outlet will already be in the right spot next time).
