Ok it is another topic about <which app> but not about “best”.
I need help with it.
Ok, we have two very powerful node-based compositor apps. Result of those guys actually could be the same. The question is about job and the applicability of knowledge in studios pipelines. Time to time I see vacancies in VFX or cinematic or something like that with the Nuke in the requirements. I am afraid of “putting eggs in Fusion bag”.
Does any studios use blackbox soft at all? Maybe anybody know approximately percentage of Nuke, Fusion and others comps app in real studios? 
What is the position of Fusion in the industry? Other compositing apps? Chances to get a job with fusion in the resume?
p.s.: My primary cg package is 3dsMax and experience in Fusion is about 2-3 years. Really like it and have no problem with it. Working with small advertising and business video. Now i am try to move in VFX.
