Which venue is currently the cheaper side of the same player props, de-vigged and counted live.
Right now BeatVig prices 185 player props at both. Sportzino is the cheaper side 68% of the time (127 of 185), and Parlayplay is cheaper on 54. This is the board as it stands at 03 Oct 15:17 ET, not an average over any period — BeatVig measures live prices and keeps no price history.
Sportzino and Parlayplay are both sportsbooks: each posts its own line and keeps its margin inside the two prices rather than charging it separately. Which of them is cheaper is not a constant and is not something this page asserts: every prop Sportzino and Parlayplay both price right now is converted to the implied probability of the same outcome and counted below, so the answer moves with the two boards rather than with the date this page was written.
Counted above: every prop Sportzino prices lower than Parlayplay. Listed below: the ones that also beat a de-vigged fair price, which is the stricter test and the only one worth acting on.
