There is actually a "who to vote for" quiz at https://www.wahlhilfe.li/ which is full of important questions like "should we increase financial support for the ski lifts in Malbun?" but is otherwise fairly helpful as it functions as a sort of microscope in order to help you detect the minuscule differences between the FBP and VU (they mostly agree on the ski lifts).
Oberland: I've got FL politicians on eight of the first ten spots, except for #5 and #10 where I have VU.
Unterland: FL on the first four spots, then largely VU except for #5 (FBP) and #9 (DpL).
