Why esri.geometry.getLength() and esri.geometry.geodesicLengths() are incompatible?

Hello,
When I calculate length of 2 points in METERS in webmercator SR, I received inconsistent results with esri.geometry.getLength() and esri.geometry.geodesicLengths():

esri.geometry.geodesicLengths() result gives a number that is 15%-20% lower than the result of
esri.geometry.getLength().
On what function should I rely on?
Why this happens? what is more accurate?

Thanks!!!!
