Stock camera vs vignette vs fx zoom

[RBrown9180]

So I posted this in the app forum but got no responses. So I figure I would try here since I know my fellow epic owners won't let me down. How do vignette and fx zoom (the paid versions) compare to the stock camera when it comes to taking pictures.? I know they have amazing editing features but is there a difference when out comes to just using the apps to take pictures? Secondly, which of the two apps is better, vignette or fx zoom (paid version of each in question here). Thanks in advance.
