How to tell them apart
だけあって comes before the result or evaluation, explaining why an outcome is natural given a known premise (お薦めだけあって美味しかった). だけのことはある comes after the fact, commenting that someone's status or effort is justified by what you observe (飛び回っているだけのことはある). Swapping them is unnatural because だけあって sets up an expectation, while だけのことはある confirms it after the fact.
- だけあって Use だけあって when you state a known reason first, then add the expected result that follows from it.
- だけのことはある Use だけのことはある when you observe a result and judge that the person's title or effort is well deserved.

だけあって dakeatte
Just as one would expect, befitting the status of
だけあって expresses that something lives up to its status or reputation, meaning a quality follows naturally from what someone or something is. It attaches directly to nouns, and can also follow phrases like という, as in 趣味というだけあって. It often appears with さすがに or やっぱり to reinforce the 'as expected' nuance.
-
さすがに偉大な学者だけあって、彼はその問いに容易に答えた。
Like the great scholar that he was, he answered the question easily.
-
彼はボディビルが趣味というだけあって体がガシッとしている。

だけのことはある dakenokotohaaru
It's unsurprising, or the effort or money paid off
だけのことはある expresses that something lived up to expectations, so the result is no surprise or was worth the cost or effort. It attaches directly to a plain-form verb, as in 行っただけのことはある. The tone is often casual, especially in speech.
-
彼はさすが大学に行っただけのことはある。
He did not go to college for nothing.
-
彼は留学しただけのことはある。
He hasn't studied abroad for nothing.
