Hi!
We are curently working on improving the situation and make comparisons easier.
Regarding the libraries you mentioned:
SYNCHRON-ized Solo Strings contain the same instruments as VI Solo Strings I + Solo Violin 2 + Solo Cello 2. The content of the Solo Strings II library is not included.
SYNCHRON-ized Woodwinds: It contains a collection of the most commonly used instruments from Woodwinds I + II, but far from all of them.
Also keep in mind that you can always upgrade from the VI instruments to the SYNCHRON-ized variants of these libraries. You can see your personal upgrade discount on the product page as soon as you own these, or make sure you are logged in on the page and add multiple libraries to the basket, to see the discount there.
My suggestion: With the curtrent sale you can't go wrong with the VI instruments, especially when you can upgrade these at any point in future :)
Best, Ben
