Alright, this is something I've thought about for a while with respect to comparisons between the German and British or Australian and Estonian electoral systems. Some of these are fairly simple to understand (say the French or British double or single FPTP) while others -- such as the German double list representatives which also get rebalanced in the end (I may have misunderstood this, but that's not the point) -- are less so. The Dutch and Estonian D'Hondt formula options go under this as well in my mind, because I don't think that it is easily understandable for the voting person to know who is actually likely to end up in the parliament even if the final composition of the parliament is more in line with the national voting tendencies.
And as it also seems that the German/Dutch systems are more representative of the people (if the criteria of representativeness is the number of votes cast to the number of seats in the parliament) than the generic Westminster systems, I would like to know if you can think of any examples which are contrary to this where a simple and easily understandable system provides a country with a representative government (based on the criterion above of seats in the parliament being roughly equivalent to the proportion of votes they received).
I'll add to the end that the German system feels the fairest to me based on this criterion, but I still don't understand it though I've done some in depth reading on the principle of re-allocation of seats. Also, their majority parties do get at times a considerably higher proportion of seats than their overall vote share (if I've read it right) so this is probably not objectively correct when compared with all the possible examples (which I have not done).
As a second addendum, I would note that such a system would not necessarily have to be effective. I think it is understandable that with an increasing number of parties in a parliament, the ability to govern with less parties decreases as has been illustrated in history (several European countries in the 1920's). However, the effectiveness of the resultant government is not a part of this question though be interesting to consider additionally.
