This matters because 〜ばよかった is retrospective. It is not used for future advice — only for looking back and feeling that a different choice would have been better.

  • Compared with ばいい, it carries a different weight and implication.

ばよかった vs ばいい

Both ばよかった and ばいい can express should have, but they are different.

ばよかった
expresses regret about a past missed action
はやればよかった。
I should have gone to bed early.

ばいい

はやればいい。
You should go to bed early.

If both translations seem possible, check the tone. Is the sentence retrospective and regretful, or is it giving advice? The context tells you which grammar point is natural.
