I have the cellular. While I don't technically use the cellular features often, I like being able to go for walks/hikes without my phone and knowing I can contact someone if need be, or reply to anything urgent. streaming music is nice, but I suppose I could just download what's needed to the watch itself. I only pay $8 a month on t-mobile after discounts, if it was more I might reconsider.
Edit: Also, because I have cellular on my watch and don't have to always carry my phone, I upgraded to the Xs Max. I always felt I had to choose the smaller phones so they would fit in my pockets when walking. Now I am free
