Pros
Pro Resolution independent
All maps will be resolution independent because of procedural techniques which MapZone uses. So you can work at a decent resolution, resize when done and you have a higher resolution texture immediately.
Pro Map focused
MapZone focuses on maps which are the core components of any texture. Your diffuse and normal maps created with it match perfectly. And because it's not linear and all are related to each other, if the diffuse is modified then all the other maps will sync automatically.
Pro Not only a Photoshop plugin, has a lot of other hosts
Pro Several filters
Filter Forge includes a lot of filters and each of them has several presets. Filters are grouped into different categories (Organic, Patterns, Creative, Distortions, Photo, etc...) so it's easy to locate them.
Pro Large online library of filters
The website has thousands of filters available for download. This is the only thing that makes the basic edition feasible.
Pro Standalone application or PhotoShop plugin
Filter Forge can be used as both a standalone application and as a plugin for PhotoShop.
