It Depends
Hope this reply isnt coming super late. Just came across this thread and thought Id share. AND I hope I dont bore you with this.....
I've been using FL Studio for the past 10 years (since version 2.7 - currently on 10) and inspite of being swayed a zillion times I keep coming back to it. I own
ProTools8 and Cubase5 as well and tried using Reason3 ( now I just rewire). I tried a hand at
Live 8 but just couldnt work my way around so got fed up and gave up on the trial version itself.
To be very honest, FL 10 is GREAT for any kind of music if you are using a lot of VSTi plugins, loops, and the audio recording is relatively less (I only do vocals.....lots of harmony multitracks though). FL's workflow is made in such a way that its great for production. It can do simple stuff and it can also do some complex stuff which most other DAW's cant. I love the internal controllers which can be used to automate anything internally. I use the midi chop, arpeggio and quantize functions ALL THE TIME.
Now the downside - My experience has been that the FL mix buss is somehow different than say PT or Cubase. Although I end up using it for smaller projects (like ad jingles which have a short turnaround time), but for serious stuff which is quality centric (like albums, background scores etc) I finish the writing/arranging/programming in FL and then use the 'Split Mixer Channel' feature to get high quality WAV files of my tracks and then MIX them in Pro Tools.
Also, like someone else in the thread pointed out, as an audio recording DAW its not great because the workflow is not designed that way. When I have to record a live band or work with mostly live audio I find Pro Tools or Cubase MUCH easier to use.
So now after all this....to answer your question, I'd say if you are going to be working more with Live audio recording, then surely Cubase
if the aim is to produce lots of EDM, hip hop, dubstep, DnB, Rnb, Pop, then FL is my pick.....I haven't really used
Ableton Live, but I doubt it can hold up against FL. Most of image line synths are kick ass...plus I use
my Native Instruments Komplete a lot. Kontakt is my favourite for Acoustic type sounds. This increases my sound canvas and affects my production quality.
DAW determines my workflow and helps me to get whats in my head out to my speakers in the quickest possible manner. My DAW allows me to experiment with sound and come up with something fresh (sometimes something boring but different). My music is me. My sound is what I want it to be. People made the best music on a four-track tape recorder.
