Well, I have to say this: no DAW is superior to its competitors. It’s just a matter of taste. The best DAW is the one YOU feel most comfortable working with. Sure, every man vouch for his favourite music making software and keeps telling it’s the only choice for this-and-that type of music. But like I said, it’s all just a matter of taste and preference.
What you need to do is to download the demos and test them throughly. That’s the only way to find out which DAW is the best.
However, I’ve been in the electronic music scene for some time now and IMO there seems to be four music making software that electronic music producers favor quite a lot: Logic Pro (only for Mac) and Ableton Live are probably two of the most popular DAWs in many professional electronic music studios. Majority of well known artists seem to use either Logic or Live.
I personally use FL Studio (been using it for 10 years now). I also know lot of popular producers use FL Studio (EDIT: as with always, you can’t be 100% sure with these “who’s using what DAW” -type of things. Only the producer can tell you for sure. Be noticed that I base the following “claims” on what I’ve read from the net on various different sources) : BT, 9th Wonder, Boi-1da, Basshunter, Deadmau5 (EDIT: FL at least to some extent (?) alongside with Ableton Live and other DAWs), Mike Oldfield, Tim Berg (AVICII), Afrojack, Audiojack to name a few. It has also been voted as best DAW by MusicRadar users in 2011 and 2012 and I could give you thousand reasons why FL Studio is the best DAW, but that would be just a my opinion. It may work for me but not for you.
I also use Ableton Live (but not that much though). Lot of DJs use Ableton Live on stage (and for podcasts, etc) so it’s an awesome “live” tool, but also very good for music production as well. Many big name artists use Ableton Live for production: Daft Punk, David Guetta, Gabriel & Dresden, Pete Tong, Rennie Pilgrem, Richie Hawtin, Sasha, Skrillex, Knife Party, Armin Van Buuren (alongside with Logic Pro) and the list goes on and on.
(ADDITION: it doesn’t actually matter who’s using what.. what’s really important is what YOU feel comfortable working with)
Reason is popular too. But there’s one major flaw in Reason: it doesn’t support VST which is a standard in most modern DAWs. That means you’re not able to use any additional virtual synth plugins or effects in it. However it has some pretty good virtual synths and effects built in so you can definetely create high quality electronic music with it.
Then there’s Cubase which is one of the oldest DAWs and still used widely and Pro Tools which is broadly used by professionals throughout the audio industries for recording and editing in music production, film scoring, film, and television post production.
For more alternatives, look at this list of digital audio workstations.
As you can see there’s quite a lot of choices. You really need to download the demos and do some testing. When you find a one that works for you, learn it inside out. That’s the best DAW.
