To answer that, I'd have to take a close look at the various experiences in that regard.
The compensatory model I favour offers a major benefit: between 60% and two-thirds of candidates would come directly from the ridings, just like you. What makes that model appealing is that those candidates would have greater legitimacy in terms of representing the entire population in their riding than under the current system. Why? Under the current system, the people who vote for you, for example, have to be Conservatives; otherwise they would be voting for a party they don't support. So the people who vote for you, and not those who work with you, are Conservatives.
In a compensatory system, all the constituents could vote for you if they felt you were the best person for the job, because it wouldn't influence the regional outcome, which would be proportional. In that case, you would go to Ottawa not simply as the person representing the Conservatives in your region, but as someone with the support of many constituents who voted for you despite choosing another party in the second vote. That would be perfectly legitimate because that's how the system would work.
