Just pick one.
Just starting out, you have no idea what's going to work for you and what won't in 6 months. Capabilities are all basically the same. The difference is workflow and what plugin formats the DAW uses…which changes how easy/cheap it is to get anything that doesn't come with your DAW.
My advice is to look at some beginning/intermediate tutorial videos for as many as you can find…and then go back and watch them again as you start to notice things kinda making something like sense. Whichever one seems like it jives with the way you think is the one you should use.
I've owned or used Ableton Live, Reason, Pro Tools, Logic, Renoise, and Ardour. And I've tried several others like Digital Performer, Cubase, StudioOne, and Reaper. Pro Tools makes the most sense to me, but I'm in the minority of dance guys that's true for. Something about it just makes sense. That and Maschine. Maschine is awesome.
But, seriously, before you clutter your hard drive with demo after demo that you can barely figure out, I say watch videos. Or just stick with Ableton until it pisses you off (if it does…a lot of people love it) since you have a free copy of Lite.
