Do try out Radiator, Vince! It rocks!
Era, the video is quite nice, but it tries to fool the audience. The tracks are all recorded very well, which is never the case with home-recorded material. In our reality we have to do a lot of fixing before we can do the mixing - and that's at least tedious, if not completely impossible, with Ardour/Mixbus. The video (of course) does not mention any of the drawbacks/insufficiencies of Ardour/Mixbus (and there are heaps of those).
And while automation is possible with Ardour, it is extremely uncomfortable.
IMO the DAW is no alternative to any "real" DAW at all, but I love the saturation from the channel strips. I spent 40$ to get that, and that's a decent price I can live with.
