I agree that sentences are generally superior to vocab. Vocab cards are extremely problematic once you go beyond beginner level, because words can (and often do) have multiple translations in both directions. This could be because there are multiple words meaning the same thing, or because a word has multiple meanings.

For example if the English prompt is "watermelon" - are you supposed to recall the Italian word cocomero, anguria, or melone d'aqua (all of which mean watermelon)? If the English prompt is "bank" - is that a place you deposit money, a river bank, to bank (turn) a plane, or to bank (count) on something happening? You end up having to build in messy hacks like giving clues in the prompt as to which translation is intended (which means you memorise the clue instead of the word) or having cards for bank(1), bank(2), bank(3), and bank(4) which becomes very tedious for recall. Sentences mitigate these problems somewhat.

I now only use vocab cards for object nouns where there's only one important translation, and mainly because I can put pictures on these cards so that I'm learning from e.g. the concept of an orange instead of the English word for orange (which saves you the step of mentally translating when you aren't yet fluent with the word).
