In what way is the character of sir gawain different from other epic heroes such as beowulf?

There are a lot of differences between Sir Gawain and Beowulf.
1. Sir Gawain is a mere knight, and Beowulf is a prince.
2. Sir Gawain is from a Medieval tale, while Beowulf is from an Anglo-Saxon tale. 
3. Sir Gawain humbles himself down and says he's feeble minded and of the least strength between all the knights, and he strongly desires to take the Green knight's challenge to avoid risking Arthur's life and put his less valuable one at stake. Beowulf is often praised for trying to pursue his own personal goals, and his strength and greatness are admirable as well.
