Thoughts on Steven Wilson's side projects ?

I also have all of Porcupine Tree including Tarquin's Seaweed Farm. I've heard a few of S Wilson's side projects (Altamont, Blackfield and solo) and for the most part I don't think they're as up to snuff as PT though I do like Blackfield's first (II was Ok, Welcome To My DNA is just so-so) and I really like Steven Wilson's latest solo Insurgentes, I think it's every bit as good as the best Porcupine Tree albums.
