I have ableton and studio one. I like ableton for writing because of the session view. Each track can have a series of clips (loops) of varying length. They can then be played against each other and even dumped to a time line.

I have a push, which comes in handy for triggering clips and sequencing on the fly.

The routing is a bit interesting, and can be a mess sometimes. For example, a track can have an instrument rack with more than one instrument, so I can hard pan two of same instrument, each with their own effects, etc, and feed that into one track for a widening effect. You can even send the midi from each out and loop the audio back in. So that's a bit diffent than pro tool or studio one where you'd need multiple tracks.

Max for live is cool too just because of the number of home brew instruments and effects available.

I export midi and audio and mix down in studio one though. Having a classic mixer with channel / bus structure each with an FX rack feels better suited for that purposes. Plus S1 has a great mastering suite too.
