That's kind of a loaded question, and you are missing quite a few packages as well. If you are basing the poll soley on power and price is of no concern, then my answer is Catia.
If you are talking 2.5D components with similar features and such I would say Gibbscam.
Each and every package has it's own strengths and weaknesses. The question to me is a bit vague, and the selections not in the same category. It's not really fair to put something like OneCNC up against Catia. Two totally different leagues. That's like asking what's the best car out there, and putting in a Mercedes SLK550 against anything from Kia or Hyundai.
