Agreed, Ultra is the only choice for me. I waited and waited, almost bought the Series 7 45mm last year, but glad I held out on the Ultra. My Series 5 is still fast, runs super smooth, no issues except battery doesn't hold up nearly as well. Maybe 10-12 hours tops depending on how I use it, and it's the non-cellular model. I mountain bike and spend time out in the mountains so was wanting a cellular model (I'm never so far out that there's no cell service) and the Ultra just ticked so many boxes.
