Novo is a very different beast and I love it. One of my best purchases. The strings designer is awesome.Nice comparison. I have to say you really can't go wrong with any of the libraries (with the possible exception of NOVO, which doesn't seem cut out for this type of thing). My favorite is the SStS and Albion One combo. I use that combo myself and it's quite beautiful. I also prefer SStS alone—and I say that not because I own it, but because it sounds the best to my ears, especially on the faster passage. SCS sounds very nice, too, but so do the 8Dio entries. CSS was a bit of a disappointment for me, however, but still very nice.
Generally speaking, they're all good.
All recent libraries are truly excellent. We are so lucky to live in this day and age.
