I think this is almost impossible to answer.
Would I pay $100 to have a CTS over a Maxima for six days? Yes, absolutely.
Lacrosse over a Genesis? Not a chance.
This is a real dilemma for me and it ended with me taking a full-size rental, eventually getting fairly lucky with a Malibu LTZ, and apart from the lack of a V6 engine, not feeling that I'd missed out at all compared to a Lacrosse.
