STANDARD is great, ULTIMATE is Awesome
This IS a great collection for most, I got the wrong one.
Standard has an incredible collection of:
Drums / Synths / Guitar tools / Piano / Tools to 'Tweek' everything / Unique World Instruments / and much morr
Ultimate also includes Orchestra Instruments (morr for what I do) and to upgrade was only $400-$500 morr.
Kontakt 5 is definitely helpful for anyone and is included w/ both. I benefit because of the death of GigaStudio. It will convert GiG samples, and many other formats, into NI friendly .nki instruments (patience required)
Guitar Rig is like having a 12' Tall flight case filled with morr Rack Mount Amplifier 'Heads' and FX then I've seen since 48th St. NY, NY, ...but morr than enough, is NEVER too much.
Anyone that chooses this Version will definitely be happy with all of the Plug-In, VST, AU, RTAS, Standalone, etc... because of the flexibility. You might wish it had something unique/specific to your personal tastes and/or experience, but it would be hard for any Company to put every sound ever heard into one package. NI tried, and the quality they provide may not be the ABSOLUTE BEST ever heard, but the Price is way below that kinda stuff ( K8$1000 )
I believe that it's morr for the $$$, than most of their competition!
Good luck in all that you do!
