I don't even feel like getting into this, but it looks like the troll is winning: Parameter Modulation, unlimited nesting/grouping/takes. Dynamically create and split audio channels on one track. Mixing of MIDI and Audio in one track. Video editing support. Surround Sound and (more multichannel) mixing. Scriptable with LUA. Includes it's own DSP scripting language (Jesusonic) with hundreds of included (and source available) tools made with it. Great support for odd or rapidly changing time signatures. Rock solid latency compensation (looking at you, Ableton). Ability to undo even after saving (looking at you again, Ableton). Completely theme-able.

Reaper isn't a perfect DAW, none of them are. But it's up there with the rest and has some features others can only dream of.

Reaper is officially supported on OSX and unofficially supported on Linux. Many VSTs run fine under Wine.
