While I can't comment on most of your comparisons cos I don't have any time in Schwiezers I can say that the comments about Robbos having to be treated gently from a mechanical point of view is absolutely incorrect.
If you get see the hammering they get when used for mustering and general station (aka "ranch" to USA'ers) work in the Australian outback you would never think that of a robbie again. Their reliability in rough conditions is why they are the most commonly used helicopter for mustering. If they were breaking down all the time they would get replaced pretty quick with something else because down-time is lost income no matter how cheap the initial aquisistion cost is.
Overall there are no questions at all about their robustness. They aren't fragile in any way.
The rest of the points about room, stability as a training platform etc you may well be right about.
