19? How about the 117 greatest words that start with the letter X? That'd be as relevant. :P
And Live!, really... Seems to me that it's a pretty limited set of options for a first choice. For exemple, if you are scoring to picture, Live doesn't really make sense - DP, Cubase or Logic are much better options and offer much more exhaustive sets of tools.
I doubt that anyone can be as proficient with more than a few DAWs - so any such list is a non-sense. Heck I've been working with Logic for years now, spending hours with it every day, I've completed the Apple certification training manual and I'm working my way through the second one, and no matter how well I know it, I'm still figuring out things all the time and going "Wow! I can do this like that? Awesome"...
I don't think I'm a particularly slow learner, and I can't for the life of me imagine that someone would have enough time to reach a point where they can make an objective comparison. Whatever you chose to use is the best.
