Newbies Questions on Sound Libraries

I am planning to return to composing after several years of absence. Scene is quite different from over 20 years ago. I just purchased Notion4 license a week ago. Have just finished downloading its Sound Bundle, and have been reading a long the ways about current sound libraries and composing technics and environment. My primary field of interest is in classical music composition, from solo, chamber to orchestral music. My primary criteria to choose Notion4 over other software is the quality of the performance I believe I will receive from playing back the score. So here they are:
1. Amoung Notion's own Expansion Sounds vs Miroslav Philharmonic vs VSL Special Editions: How are the resonant qualities of the result from mixing sounds of each instruments compared. Twenty Years ago, the play back sound just biting each other out. They didn't act like the real sound waves in that they mixed and harmonized to have certain resonant quality before the result reached your ears.
From what I've observed over demos, samples and youtube, the new sound libraries seem to be much much better than before, in this regard. The patches do not sound like competing for attention all the time, as before. However, from times to times, you would find some moments in the demos and samples (from all of the mentioned libraries) that still exhibit this kind of uglyness. So this is my main concern. Which of these libraries give the best result in resonant qualities of the mixed sounds? Or, if some works must be done (seemed to be the case) to give a more natural result, which library is the easiest to work with, to achieve the better harmonized sound, under Notion4?
2. Will other libraries work as well with Notion4 as the mentioned above libraries? Such as, Cinematic Strings, LASS, EWQL, GPO, etc? Can Notion4 works with more than one library at the same time (the same moment in time)?
3. Do these libraries, working with Notion4, still have limitation in term of how many sounds or patches Notion4 can play at once? Like the old MIDI Synths' limited specs? Or it can play as many sounds from as many libraries at once, as long as the computer can handle it?
4. For VSL Special Edition Volumes, does Notion4 work with all of them, out of the box, (Vol1, Vol1 Plus, Vol2, Vol2 Plus, Vol3 and Vol4)? Would Notion4 work with their newer libraries, such as Vienna Dimension Strings, also out of the box?
Please bear with my newbies questions. These questions are not meant to put down some products in any other way. I just want to have a bit smoother glide back into writing some music.
Thank you.
