Sonar is the best "daw" out there now. ( vs Pro tools, cubase, reaper )
But...
I see albeton as more of an audio workhorse instrument ..it pulls you in to the marvels it offers and encourages you to use it as an 8/16 bar loop instrument. It is bloody sensational at that and will add way more to an electronic musicians sonic arsenal than another hardware synth. But its ability to produce stuff like sonar is just not there on its own.
They are both great products and should not really be compared alongside each other. Live 9 will offer audio to midi conversion, atomics the glue compressor wherever you want it and design your own synth/plugin on top of the existing jaw dropping workflow. There is nothing on the market that will allow you to process audio like albeton can.
I think albeton is as important to dance music production as was the 808,303 and 909. A truly amazing piece of software for electronic dance music. My NI maschine is so sacked after demoing this for a couple of days.
