だけあって

Expresses that a result or quality is just what one would expect given a certain fact, such as status, experience, effort or reputation. It is usually used to praise: 'as might be expected of…', 'befitting…', 'no wonder, since…'.

Used in both speech and writing to evaluate someone or something, typically with admiration, by linking an impressive result to a known background fact. It suits comments on people's skills, products, places and reputations. Unlike にしては and わりに, which mark results that go against expectations, だけあって marks results that match them.

• だけにN2「だけに」can also indicate that a result follows naturally, in which case it is interchangeable with 「だけあって」; it can additionally express deeper disappointment when the result turns out opposite to what was expected, as in 「期待していただけに残念だ」— a usage 「だけあって」does not have.
• だけのことはあるN2「だけのことはある」usually appears at the end of a sentence as an overall evaluation, and the basis can be left unstated; its conjunctive form 「だけのことはあって」is close to 「だけあって」and the two are roughly interchangeable. However, it is generally used only for positive evaluations, not for negative outcomes.
• からこそN2「からこそ」means 'precisely because...' and emphasizes the reason itself, often one the listener would not have thought of, and it usually pairs with 「のだ」at the end of the sentence; 「だけあって」instead highlights a result that lives up to its reputation. After nouns and な-adjectives it attaches with 「だ」, and the two are generally not interchangeable.
• にしてはN3「にしては」indicates that the actual situation does not match the degree you would expect from the preceding item, carrying a sense of surprise, and it works for both praise and criticism; 「だけあって」means the result is commensurate with the preceding item. The two meanings are opposite and cannot be swapped, and when a な-adjective takes 「にしては」, no 「な」is added.
• わりにN3「わりに」indicates that the result does not match the expectation formed from the preceding item, and it can be either better or worse; 「だけあって」means the result lives up to its reputation and matches expectations. The two meanings are opposite and cannot be swapped, and when connecting to a noun, 「わりに」takes 「の」while 「だけあって」does not.

だけに also links a fact to a fitting result, but it can introduce negative or intensified outcomes, whereas だけあって is mainly praising. だけのことはある expresses the same idea sentence-finally, and からこそ simply emphasizes a reason without the 'as expected' nuance; にしては and わりに express the opposite, a result that does not match expectations.
