The back up system is good and the price is good too which earns the 2nd star. But in my country, Google is blocking most of the benefits (no youtube music, no travel benefits, no VPN....). So it's basically a a glorified Google Drive. Honestly I only keep using it because it for the minimum amount of convenience it provides as it is linked to my gmail account directly. Otherwise, it's the same as other cloud storage apps. Edit 1 : The difference between One and Drive are mainly the benefits previously mentioned. Adding small features will not bring any meaningful value to me or other users unless it's one of those benefits or new ones. So simply make sure that they are available worldwide and not to a small number of countries. If you are targeting my country with One then make it worth the money we are paying. 1 USD coming from USA or a third world country should not be buying products of different values. If you don't consider that country has the infrastructure for Youtube Music then, you shouldn't be introducing Google One to it in the first place.
