気まぐれ focuses on the capricious, mood-dependent nature of an action, while 思い付き emphasizes the suddenness of the idea itself. 気まぐれ is more about personality or consistent inconsistency; 思い付き is a single instance of a sudden thought.
彼は気まぐれな人だ。
He is a whimsical person.
それはいい思い付きだね。
That's a good whim (idea).
There is no single Japanese word that covers all uses of 'whim'. Choose the expression based on whether you mean a sudden idea (思い付き), a mood-driven action (気まぐれ), or a vague reason (なんとなく). Using 気まぐれ for a sudden business idea might sound odd; 思い付き is better.
