Probably the most famous conflict that satisfies your requirements is the conflict between
"Ptolemy system" and "Copernic system", though few people understand this even today:-)
This conflict became so famous because of the intrusion of a non-scientific authority, that is catholic church. From the point of view of astronomy, there are two aspects:
a) the choice of coordinate system. We are taught in elementary physics courses that this is indeed a matter of choice, of convenience. Some coordinate systems are good for one purpose, others for another purpose. Heliocentric system is by far more convenient when you want to write equations of motion. But geocentric system is more convenient in navigation, where they do not care about "how planets really move" but in "how this looks from the Earth".
b) the more important question whether the orbits are combinations of circles with uniform motion, or Kepler ellipses and the motion obeys Kepler laws. Of course, the discovery of Kepler's laws was a really great discovery (probably more important than the Heliocentric system), because they led to the discovery of the law of gravity, etc., and because they have much simpler mathematical formulation. However when people try to solve the equations of motion for more than 2 bodies, they obtain a solution in a form of
a trigonometric series of functions depending on uniformly changing angles, which is
essentially the same as Ptolemy did.
So you can think of the final result as a representation of the motion as a combination
of epicycles.
So in this case we really have a kind of synthesis after a long controversy.
Of course this conflict had also other significance beyond astronomy.
I don't want to discuss philosophical consequences.
The interference of the church into purely scientific matters undermined the church authority, so I would say it lost the cause in the long run.
On the other hand, Galileo is also not so innocent in triggering this conflict. (Copernicus and Kepler did not have any conflict with the church). And the main "proof" that Galileo presented for "moving Earth" was wrong. So it would be much more reasonable on the part of Galileo to hold Copernicus view that the difference between the two systems is mathematical, the choice of the coordinate system, which after all is closer to the truth.
Galileo's main "proof" was based on his totally incorrect theory of the tides which contradicted principles of mechanics he discovered himself in the young age.
