How to decide

Choose 差强人意 when the sentence points to barely satisfactory, better than expected, or acceptable despite flaws. Its tone is guarded approval, and the safest first test is whether the context resembles guarded review, performance judgment, quality threshold.
Let 一模一样 when the sentence points to exactly the same. Its tone is neutral descriptive, and the strongest clue usually looks closer to visual comparison, school comparison, product change.
Their overlap is limited: both appear in everyday-speech and learning situations. The difference is not the Chinese topic label but the job each phrase performs in a sentence.
For English translation, start with barely satisfactory for 差强人意 and exactly the same for 一模一样, then check whether the surrounding sentence needs praise, warning, correction, or neutral description.

Wrong choice checks

差强人意: Do not translate it as simply disappointing just because 差 appears at the beginning.
一模一样: Do not use it for vague similarity. Use 很像 when the match is loose.
Do not choose by literal image alone. The animal, object, or story picture helps memory; the sentence still decides the meaning.
Do not use this comparison as a synonym table. If neither phrase fits the speaker, object, and context, a plain English explanation is better.

Practice prompt

Write one sentence about guarded review using 差强人意, then rewrite the same situation so 一模一样 becomes correct. The rewrite must change the cause, tone, or outcome, not only swap the Chinese words.

差强人意

This report is not perfect, but overall it is still acceptable.

一模一样

These two pieces of clothing look exactly the same.
