Is the Milky Way at least 2 to 3 times as massive as M31, the Andromeda Galaxy?

New measurements of the Milky Way shows our galaxy to have a mass of 1,500 billion solar masses within a radius of 129,000 light years, not even taking into account all the stars and stuff outside this diameter since the Milky Way is estimated to be somewhere between 150-200k light years.
