There is no program out there that's "the best." There are, instead, a whole bunch of options which might fit your needs and workflow better.

Look up: (and this is just a short list)

Pro Tools

Reaper

Logic Pro

Cubase/Nuendo

Sound Forge

Triumph

Audacity

Sonar

FL Studio

Studio One

(You already listed the bottom two)

My suggestion would be to try a demo of each program and see what you like best. See what type(s) of music you want to write. What is your budget you want to spend? What kind of features are you wanting out of the DAW? Do you want bundled FX and instruments or 3rd party? Once you found the one that works for you, buy it and learn every thing about it you can. It's hard to predict which programs are going to have a long future and which ones will not. For example, I still use Peak Pro and, overall, enjoy it but the company closed down. It was around for a good while before that and had a good number of users.

Thanks,

If you want to be able to send your music in to another studio and have them edit your work, go with Pro Tools.

Any professional studio will be able to directly work with that.

If you don't need that - looking just for yourself, as the post above says, lots of good options out there.

Be sure not to just look at the base software, but what plugins it supports.

Well, honestly, I know more and more pro level studios who are using other DAWs as well these days. So that may not be as much of a factor. Plus exporting stems and MIDI is really easy to do so sharing music from one DAW to another DAW really isn't much of an issue.
