From what I've been told by a couple of the corporate guys at my company, the -145 costs a lot more than a -135 to operate. I'm not saying that's a reason to pick them, but it's an interesting data point.
As for Systems vs. Stick skills, the fleet will want Systems guys, but what people have to remember is that it's primary flight training. You have to at least try and grasp the fundamentals of flying a helo. That will help you later when the flying part of the automation fails later. And it will fail, eventually.
