For me, growing up with Logic with it's linear arrangement, I still haven't quite got as fluent with Ableton Live’s way of working, I just can't seem to make the connection between the clips and the arrange layout. With Bitwig, it becomes blindingly obvious, with the clip launcher able to display with the arrangement , as well as the more familiar Session type view - so taking a track you created in linear fashion, you can build an arrangement from clips by dragging sections from the arrangement to the clip launcher - I get it!
Also, there is the same warping type engine for dealing with clips both in clip and arrange mode.
Looking at the basic feature set, additional operational features are worth checking out - with per note automation as one, you can tweak parameters on a per note basis with instruments that support it, additionally the Multi-Layer MIDI/Audio editing looks pretty useful, especially for those who create multi-track beats - you can switch in and out additional layers from the editor. Multiple documents can be open, allowing drag and drop, copy and paste between arrangements - this is something I do all the time in Logic and other DAWs but not currently available in Live.
Hybrid tracks - allowing instrument and Audio together so you can bounce in place.
Device nesting for creating complex processing and instrument setups - store and recall for later.
Modular By Design
Under the hood of Bitwig lies the real power, all the effects and included instruments are built using a modular environment - somewhat similar to NI Reaktor, in Bitwig Version 1.0, this is hidden from the user, but in version 2 we will be able to dive in and modify existing instruments or effects and instruments as well as create our own with astonishing granularity. Plans appear to be forming to create sharing or even being able sell your creations.
