Currently, I am using Samsung Gear S. I am thinking about switching. I can't decide between Modular Smart watch and Moto 360. I really like the style of Moto 360 but upcoming Modular smart watch seems to me advance level watch then Moto 360. On this smart watch user would be able to add new blocks and each block will cost $20-$30. Which is not possible in Moto 360. So I am really confused. Which one should I buy?
