Did I mention I also love their GUIs…? Happiness is a warm (hot!) plug-in bundle. 😛
Probably the main draw for me with Fabfilter plugs. You can have so many features in one host or plug but if accessing it all is a hassle I would go with a much easier interface any day that offers less features if need be, as I would get much more out of it anyway.
Thankfully the FabFilter plugs have exceptional GUI’s and very powerful features. 🙂
