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 a result is natural or expected given a status, background, or effort, conveying praise or acknowledgement like befitting an expert. It attaches to nouns with no extra particle, as in 専門家だけあって, and to the plain form of verbs and adjectives, often the past form like 住んだだけあって for completed experience. The clause after it describes a positive or neutral outcome that matches expectations, not a surprising or negative one.

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 says that a good outcome is no surprise because enough time, effort, or money went into it, often translated as worth it or paid off. It follows the past form of a verb like 練習しただけのことはある, an i-adjective like 高いだけのことはある, or a noun phrase with だけ like 有名な店だけのことはある. It is used for positive evaluations only, and the final ある becomes あった when looking back on a completed result.
