I have the pleasure of teaching FCPX and Premiere Pro and even better that I get to work with all three almost daily in Broadcast, Film and Corporate level.
I do my best to show the students the differences and commonalities.
Honestly in the last few years its 50/50 with Apple and Adobe as far as user traction.
The Avid users are mostly legacy owners that have passed it down the line.
I am sure its different in other parts of the country.
IMHO, FCPX users are up and running with their personal projects.
Now as far as negatives go, last night I had to show the Premiere Title Tool…nuff sed 😛
