I have the VivoActive HR (also where did you find one for $150, that's amazing considering mine was $250 and still is on the Garmin website..) and I think it is one of the best purchases I have made.
-I have never had an issue with taking more than 30 seconds to acquire a link
-Long battery life, even with the constant monitoring of HR
-Charges amazingly fast
-Strangely comfortable band, almost more comfortable than my Citizen watch.
-Cool features such as monitoring of sleep, (deep sleep, light sleep, etc...)
-The face itself is very nice/bright.
-The amount you can customize the data fields for runs is great
- Holds information for up to 8 runs at a time, though with Garmin connect on your phone (automatic transfers make this easy) you can look at them whenever.
-Overall just a wonderful watch.
