Any ENB config that uses the latest version should have the same options for quality and available features. Generally, different configs simply change visual options, such as light intensity, color saturation, etc. So, I guess it's really just your personal preference as far as which ENB configuration you go with. I know that probably isn't much help as far as making a choice, but I'd be happy to assist you with options in enbseries.ini that increase/decrease the quality of things like shadowing, ambient occlusion, indirect lighting, and a few others. Changing these can sometimes improve the visual appearance of your favorite ENB config.
