I really love the Fabfilter plugins. Besides begin very easy to use and filled with great features they work really well with Cubase and Wavelab being available as VST3 (with side chaining just like the Steinberg plugins) and in 64 bit. Licencing is based upon challange response so there’s no iLok.
I suggest you try the demo versions of the Fabfilter plugins to hear and try for your self. They have released a really great set of tutorials for their plugins on youtube: http://www.youtube.com/user/fabfilter
