I'm struggling to pick between the two, because the main differences don't matter to me. Don't care about screen, battery life, GPS, or smart features. I'm not a runner. Mostly I walk, hike, and do strength training.
I care mostly about health stats because they help me keep my chronic illness in check by helping me know when I can exercise and when I need rest. Body battery is the most helpful feature on my current watch (Venu sq). Instinct 2 has training readiness which I think would be helpful, but I have read that body battery on the 255 is updated/more accurate? Are there any other differences in accuracy or features when it comes to health monitoring?
I like the instinct 2 most for cheaper price and and ruggedness, but I wouldn't mind the appearance, animations and muscle maps of the 255. So I'm completely torn.
