I generally use next when I know that I need to realise anyway soon. As Laurent said: this happens a lot in loop. Would we use rest, we would have to check with seq whether the sequence is exhausted. If we do this anyway, we can just as well use next and save the seq call. Another such scenario is when you need a look-ahead in a lazy sequence. Eg. partition-by needs at least one item look-ahead in order to decide whether to split groups or not. Then you can also use next since you realise the next step of the input sequence anyway.
