For me the big thing is the case where you want to use a list comprehension with a somewhat expensive function:

   [func(x) for x in values if func(x) < 10]

You could break this into two comprehensions, sure, but it's annoying. With this:

   [result for x in values if (result := func(x)) < 10]

Agreed. List comprehensions are where I see them being the most useful and where, in the past, I wished the functionality had existed.
