Been using Medibang for years now, having bought the steam version over a year ago to continue with the program.
Simple UI makes it great for beginners, however with the new "Medibang Premium" I cannot suggest ever purchasing the Steam Version at all. Having to pay for software features and then being forced to pay a subscription for features that was once free is a great way to lose your users.

wish this had an animation timeline, then the the price would somewhat be worth it
