Ableton is extremely versatile with a wide range of plugins that can expand your options in producing/editing audio.

The ease of improvisation and quick MIDI setup.

one of the most versatile DAW among those offered on the market, i think is the most powerful platform for musicians and DJs who plays live on a stage. Ableton has got a great workflow and is very easy to use it, supports VST instruments and plug-ins, i can use and program my external synth on it. Is great for songwriting, i think is the best for making electronic music. you can work with two different monitors on arrangement window and live window, some years ago this feature was not supported, now it's a powerful thing!
