They have fantastic range, deal decent damage to soft targets, and absolutely wreck enemy cities, which yields fantastic long term results. Their range makes them great at scouting, even with that poor line of sight, and also allows you to send bombing raids deep into enemy lines to cut off enemy reinforcements, or prevent those reinforcements from being produced in the first place. They certainly aren't for every situation, but they are by no means a bad unit.
