my personal taste is cubase. well, actually its none of the above, its nuendo, but thats practically cubase. imho logic is too powerful for its own good, damn complicated and hard to use compared to my beloved n1.6, and i dont want to get onto the Mac train, so thats out. imho reason is (and i hate saying it, because its such a snobbish thing easily refuted by citing the many fantastic tracks produced entirely with it) a bit of a toy, because its non-expandable with 3rd party plugins of any format, cant record audio and cant output midi, three things which are fundamental and critical to production for me.
Note thats my deliberately opinionated slant. From a balanced standpoint, Logic is a fantastic program with ultimate power. And I get the impression from friends and forums that Reason is genuinely easier to learn than cubase/logic/etc; I've also heard you can write faster; the non-expandability is also a benefit as it improves stability and performance; and, like i said, "toy" doesnt mean it cant produce the pro results, which is the important thing in the final analysis.
So... I reckon you might get some mileage out of following what has become the "classic" path into production. Messing with Reason, doing a few tunes with that, getting to grips with the basics of synths, sampling, processing, routing and mixing. Then, when ready, you rewrire it into Cubase and begin adding as little or as much Cubase stuff to your palette as you need/want.
