i think the canimations might win out over time.
here's why
even though live seems to give users full control the animation quality sucks as we all know. but being a creative, i tend to view it like a flip book. instead of drawing out each motion, mo capping is a much quicker process. 2k adds tons of new animations each year so i think its only a matter of time when the tech arrives that will allow them to take away the puppet strings and everything will feel so organic/real people might not know what to do with themselves.
