I was surprised with the OLED move from Garmin but it feels like the right move.
I have the VA3M and I've been really impressed with it. I don't like the VA4 - the sizes are worse than the VA3 and it's so close to the Venu in price it makes no sense, unless you need the longer battery life.
The slight concerns I have for the Venu are the bezel looks odd and it doesn't seem to make the best use of the display. It's also so close to the apple watch in price I might just buy that instead. I prefer the round watch face of the Garmin and the fitness features are miles better, but the apple watch looks more premium. I hope I'm wrong and I choose the Garmin because it just works.
