PouchDB with Ionic 3 - Which storage system should I use?

Hey Yury, not sure if it is a conflict. Those statements are done on a very broad scope/scale and when it comes to a specific project - you can decide what works best for you.
Personally I tried both, both have some issues and pretty good support. In my case I chose localForage (Ionic Storage) simply cause its part of Ionic offering and working with it proved to be successful.
