I would tend to think they work better on shortish par fives, where, if you miss the drive, you have a real decision to face as to whether you attempt to carry a cross bunker more towards the green in an attempt to still get on or thereabouts in two, or one that is located more midway between tee and green where you have to decide whether to carry the cross bunker to give yourself a shorter third, or lay up for a long third.
Woodhall Spa has an excellent example of the latter, in the 9th hole, possibly the best on the course.
