To any long time MEP users using MEP 2015. I have been using the trial version of MEP 2015 and do not see a whole lot of difference between it and MEP MX. I had similar obervations for MEP 2013 and MEP 2014. The biggest difference I see is that preview rendering is much faster. I know the premium version has some extras but I really don't need them. I also see that image stabilization has been somewhat improved, but still no where near as good as the Mercalli or New Blue stabilizers that I have which were included with some other editing apps that I have. I'm really just trying to understand if there are any good reasons why I should upgrade.
