It's been a long time since I played Record Breaker so I had to read an ending summary so maybe I'm missing something, but I think the difference is that Ronaldo's ending implies the party WILL eventually fail, where as Space Marine has already crushed the Schwartzveldt seven or so times already with no signs of weakness. Ronaldo also suffers from there being an objectively better option proposed by a more popular character that the game is even named after, and probably some lingering resentment for his character from the original route.
