Do not use the fire stick for PlayStation Vue. If you are going with Amazon you have to use the FireTV. Th FIreStick tends to lag and have some other issues(crashes, video quality issues, etc).
Over all though I have been using PlayStation Vue for 4 months now on two TV(mainly using Fire TV on both) and it has been great! We had a couple of hicups early on, but they seem to have worked them all out. The quality had been very good with a few exceptions. Fast moving scenes can 'break up' a little bit some times and occasionally we get issues with picture quality, but that is pretty rare now.
The DVR can be a bit of a pain at times as there is no way to 'record' just the new episodes, it pretty much records every episode. It only keeps the shows for 28 days, so if you like to horde and binge that could be a problem. Though a lot of the channels are getting On Demand now, which pretty much fixes that issue.
Over all we have really enjoyed it with very little problems.
FYI: I run at 100Mbps.
