Anyone using the Vivoactive 4? I was between it and the Forerunner 255 music, but I think I like the idea of having a touch screen, which the Forerunner 255 does not have. I live in KS, so didn't figure I would use a lot of the fancy elevation and running settings that the higher end models have, so I find it hard to drop $500 on something like the Forerunner 955. Any feedback or things to consider are appreciated as this is my first smart watch purchase. Thanks
