I think that proportional representation and coalition governments and these aspects of consensus democracy work better because there is more negotiation and compromise. Therefore, it builds stronger consensus. If you have a majoritarian government, let's say a one-party government, that is based on between just 30% and 40% of the voters, this government actually struggles constantly with the fact of being a kind of illegitimate majority government, because it is not a majority government. It is a government supported by a minority.
In the long run, I think it is better that the principle of majority rule works in democracies. It may seem ironic or paradoxical the fact that with proportional representation, you have better majority rule than in so-called majoritarian governments with FPTP, where the governments really represent only a large minority.
