@Alexelle Lee XP-Pen Artist 15.6 Pro isn't very different from Innovator 16. The plus for Innovator 16 are design which looks better and the display is laminated.
These are the pros
+ Brighter display
+ Significantly higher resolution
+ Has USB ports and USB C
+ A lot more shortcut buttons
+ Better stand if you want to use it as your main monitor
