“Sir Gawain is a model of goodness in Medieval Literature.”
The other sentence is stronger because the word is more noble and honorable sounding.
“”Varys consented to Dany’s ruling that he should die by fire.”
This is not as strong because the meaning is not quite accurate. Varys consented, reluctantly, but the reluctance does not come through if you do not use the word acquiesce.
