They're wonderful, expressive instruments and these libraries are everything but. Woodwinds and brass are exposed instruments in an orchestra because there aren't too many of them. So if you're doing an ostinato, it will start to sound like a loop rather quickly. There's only one type of short 'bowed' articulation, and it's staccato, and it has 4 RRs. It will be pretty hard to perform expressive lines because that's just not how a string ensemble would transition from note to note. Then listen to the demos of Symphony Essentials. Listen to the demos of the East West orchestra, you can do a lot of things with that library. You can't, however, fix missing content with an EQ and a reverb, nor can you fix bad playability.
Once you set up a template, you won't have to deal with PLAY that much. You can always EQ the sound and add some reverb if it's too dry.
