The Kontakt factory library content is just okay; I hardly ever use. They are just basic sounds; not the high quality sounds that sound designers try to produce. It comes with Kontakt, so you have something to start of with, but better are other Kontakt libraries. I've got some phenomenal sounds that run in Kontakt and wouldn't trade them for the world.
The good news is that now that you have the full Kontakt, you will later be offered some pretty good sales on other libraries from Native Instruments. Session Brass, Session Strings, Session Guitarist, Symphony Series are all pretty cool. And then add libraries from
Indiginus and
Realitone, and other vendors. While there is a lot of free Kontakt content out there, you can also drop a lot of dollars as well, but there's some pretty cool stuff.
I've got the
Komplete 12 Ultimate - Collector's Edition (which I've been upgrading each version since I bought Komplete Ultimate 8 several years ago).
Of course, they key is understanding that, as Mario said, Kontakt is not a GM module; you just use it for specific instruments. In BIAB and RealBand, you have to make sure you match the track channel to the channel you load an instrument on. Kontakt will not auto-load any instruments; you have to do it manually (as I'm sure you've found out).
Also, since it's not GM, you will also find that instrument ranges may differ from standard GM output, depending on the Kontakt instrument you select. There may also be key switches. That's why Kontakt works best when used on the Melody or Soloist track, as you have much better control over the notes played. The notes from styles are based on using a GM synth, and so your results may vary. It can be done on accompaniment tracks, but you just have to pay attention to what's being generated and marry it with an appropriate Kontakt sound library instrument.
