The Amaranto and the Gauss Baron were both powerful expert mechs in their own right. It was not easy to determine which one was superior.
Any direct comparison became a lot more complicated because comparing the two was similar to comparing apples and oranges.
The Amaranto only possessed a single gun while the Gauss Baron boasted eight powerful cannons. The former was able to maneuver somewhat comfortably in space while the Gauss Baron was locked in a large and incredibly resilient bunker.
The Amaranto's lack of bulk meant that it did not possess enough armor to endure too many powerful attacks. The Gauss Baron was so thick and heavy that it could easily withstand a sustained bombardment even if its resonance shield had been exhausted!
The differences in firepower and defensive capabilities immediately determined which of the two expert mechs gained the upper hand.
