Build question.

Hello.
Firstly I'd like to apologize if I'm using the wrong forum section but I was left with the impression that the build sections are mainly used to post and discuss builds and my question is slightly different.

I want to start a marauder and I can't decide between ice crash and cyclone and I can't really find a good comparison. Can someone be kind enough to explain the pros and cons of both?
Are they both equally viable? How difficult they are to gear? How well they do on maps?
Ideally I'm looking for a build that scales a lot so that I can keep farming and improving it. I don't want to reach a "soft cap" early on that basically leaves little room for improving your character.
