The best thing about true push notification system was its price point! It literally costs less than half to send out 100k messages compared to other providers we used in our previous job at another provider where I sent 200K per month using their service alone. We were able to get all sorts of people into the loop even if they weren't part of your target audience through this product without having them optin or signup first. There really wasn’t anything bad either - just wish there could be more customization options so you can do things similar to what some enterprise level services have but still keep within budget limitations of course. If cost isn't an issue then go ahead anyway because once you set up everything correctly it will deliver great results regardless of how much traffic comes across these channels each week. Our team uses it daily as well when.
