While I would agree that lenshu3ng.tbm is the most consistent mod, I wouldn't be so generous as to say that 10 out of 10 times, the better player wins.
I'd say that between two advanced players, 50% of the time the better player wins. Think of very good lenshu players like tooorasooh(sp?), Biaker, and xJuicy. I've played each of them multiple times and I've beaten them before, despite them being clearly better players than myself.
On my best day and Biaker's worst day, I will probably beat him 2/5 times.
