Well in my opinion: If you need to export from Vue or if you need to import scenes from high end applications for render in vue or if you make money on what you do and think the better OpenGL eventually will pay back the investment in better handling speed or think that the ability to strech,bend,resize and changing the images on an allready existing plant is what makes up a greate plant editor then maybe it's something for you. Otherwise I think you could spend that extra $ for the pro version on something else, maybe a real plant editor.
