Setting aside whether they include PFAA, I'm fairly sure both Beyond Reality and InfiTech 2 include Thaumcraft, which I'm leery of since one of my earliest experiences with it involved encountering a hungry node.
I was just thinking that next time I'm ready to start a new world (which will be after I've weaned myself off of high-res texture packs (if I can), and possibly after GT 5.09 is released), I'd try using PFAA oregen instead of GT's oregen, and I figured if there was an existing modpack that had the features I wanted, it would be easier than configuring things myself.
