Well, back in September 2015 just after I posted comments above, I bought an original Moto 360 for $108 delivered. It lasted until June 2017 when the battery started dieing.
So I bought a like-new refurbished 1.63" zenwatch 2 last month (July 2017) for $89 delivered.
After a month I am in position to compare:
Advantages for moto 360 g1
* heart rate monitor (minor)
* easier to see outdoors
* stays connected to my phone over a longer range as long as phone and watch are in the house. Zen watch disconnects when Im on a different floor of my house
Advantages of zenwatch 2
* BATTERY! I can run with ambient face on use my watch heavily and have battery left at the end of the day
* android 2.0.
* speaker (on the large version)
* contrary to my comments two years ago, I now think tree zenwatch looks better.
Overall, both great watches and solid values. I think I just needed to build up my self confidence wearing a more traditional looking round smartwatch for awhile before I was ready to rock a bold square watch. Now I'm loving it.
