Hi
Personally, I would recommend BBO Series over SY-zed Special Editions. BBO libraries were recorded at the beautiful Synchron Stage. And also, there is the 2 + 1 offer this month. So, if you have 400 euros, I would recommend Orion (woodwinds), Lyra & Musca (Strings) and one of the Brass packs. It should cost you 385 euros.
Best, David
