Life is indeed confusing!  Quanta came from Polygen (Polygen turned into MSI)
and InsightII from Biosym (Biosym and MSI merged and kept the name MSI).

Quanta was designed originally for Protein Modelling, but now has Polymer
stuff and superb X-ray electron density fitting stuff.

InsightII was designed originally for Polymer stuff, but now has Protein stuff
available (well actually there are two versions available (i) life sciences,
or (ii) polymers).

The interfaces for Quanta and InsightII are quite different.  Here in York we
much prefer Quanta's!  

You'll need to ask msi.com about pricing.
