Like many have already said, it all depends on what you end up comfortable with. You'll never really know until you try making a few songs with each of them and start to understand the nuances of each software.
Personally, I've tried them all and I love Reason. For me, its workflow is second to none. As much as I love Kontakt, floating windows and constantly having to set up track routing seriously distract my process. My only complaint is that *sometimes* it gets a little difficult to find the right sound that you're looking for -- I think this is primarily because it tends to cater more to sound designers than patch fiends like myself. But as time goes by I get to know the factory sound bank better.
Not to say the FL Studio and Logic don't have their advantages, because they do. Logic Pro X's scale quantize feature is awesome, and the built-in instruments sound bloody amazing. And I personally feel FL Studio's MIDI sequencer is the best out of them all. But at the end of the day, Reason wins for me -- it's all up to you to find out which one you'll end up being most productive in.
