Ring -
1) I think the video quality is pretty good. I imagine the Pro has better than the standard version I have.
2) I got mine from Costco which comes with a year of the cloud package. I would recommend buying it there ( costco.com)
3) I don't use the motion due to the fact I have cameras outside my house. I don't need the motion. Plus didn't want the shabbos concerns.
4) Had a family member who had it and was happy. With the Costco deal, it seemed based on reviews it was best deal and best service.
Nucleus:
1) Haven't used the Alexa feature but am pretty sure it does not need an Echo. However, the quality of playing a song or using it as an echo in that sense would probably not be of the greatest quality.
2) Video quality is decent. All depends what your expectations are. For me it is an intercom first. I needed an intercom as I have 4 floors. The quality from a phone to a device is even less. In a room that has no light, it turns to infrared ( looks black and white) however, it does not change back if you turn a light on. The infrared is a new feature that I imagine will continue to improve.
3) They are all wall mounted. 3 are ethernet and 1 is wifi. I haven't seen any real difference in quality, but I can't say that I have really tested that well to give a definitive opinion.
4) The kids love it. They can call me with the touch of a button ( which can be annoying at work sometimes ;-) ), can call them up from the basement for dinner, see what they are doing in the room that has it, etc... Makes it easier for babysitters to have one button call access to you. It adds a new dimension to being in contact within your home and when away from the home.
For me, this was a great option due to needing an intercom system and wasn't able to use a wired system.
I don't have any other real smart devices that I can think of. These were purchased more out of necessity rather than my being techy. Although when people come to your home they thin it is really cool.
