Try to watch my videos , one i done about VBC ....
VBC is an exellent purchase because those comp are really good and usuable anywhere (tracks , buses , mix , mastering ect ...)
FGX is a beast but you have to master it , buying it now will certainly allow you to get FGX 2 for free soon ....
you really gotta be carefull with it ....and if you just need compression be sure to bypass the limiter and dithering ....
VCC is a cumulatif plugin witch mean you need a bunch to really appreciate what it does expet if you drastically drive it or oevrdo it (specially on the neve and trident) ..the tube is great when i need natural limiting ...if you really need sat/drive/console emu as an FX , go with NLS , if it's a subtile color , VCC
VTM is exellent ...(watch the video on it too) ....and can be subtile to really obviuos and everything bewteen ...complete set of control but not too much (versus some other like J 37 or UHE) usable anywahere from prod to mastering...
so if you're not into mastering i will go VBC and VTM , and then FGX (for master duties or quik premixes for clients) and last VCC
