I've gone down that rabbit hole, repeatedly. It's just too fascinating. Likewise, I feel obligated to bring up the Voter Satisfaction Efficiency (or index) metric that seems to be favored by the approval/range voting crowd: basically estimating how utilitarian a given voting system can be. There's a fascinating write-up of their modeling results on github, with code (python).

When it comes up in conversation (or I can work it into conversation), I push people to this - it has some great interactive visualizations
