Complement of result:完 or 好?

Question

I‘m currently learning how to form the complement of result and what are the translations of some common compound verbs. My book makes this examples:\n• 看完=to finish watching\n• 写好=to finish writing\n• 吃好=to finish eating(with satisfaction)\n• 学好=to finish studying\n\nMy question is: why does it use 完 just in the first example and 好 in all the others if the meaning it‘s always "to finish doing smth"?

Answer 1

Both 完 and 好 could be used in the complement of result, but they have a slight difference in meaning. 完 means completion, 好 means sufficient. Say you just had a slice of pizza, 你吃完了， but you might still feel hungry. Therefore, I can not say 你吃好了 in this case.

Answer 2

完 indicates finishing; 好 also indicates finishing, but with the added connotation of "and ready for the next thing", especially when the next thing requires being done with the action of the verb in question.
