That depends on what you wanted to use them for, and what you are comparing them against. Obviously they were good enough to win many battles. But if you wanted to use them for finer work like opening cans, or to defend against modern sieges, they would obviously be bad. How about rephrasing the question to permit a more solid answer?
Nuclear weapons are tools. Tools can be neither bad nor good. The only things that can be bad or good are the people using them and the purpose those people use them for.

Which Henry III - of France, England or the Holy Roman Empire. Each one had good points and bad points. None could be considered bad.

It depends on what perspective(s) you are studying - strategical/military, environmental, socioeconomic, etc. From a military point of view, sieges are good for the army that is sieging because casualties can be greatly reduced as opposed to rushing a fortified position. Sieges are bad for the sieging army because they are expensive since they can take a lot of time - soldiers need to be fed and paid, disease can spread through the army, supplies can run low and the siege can fail if it is not well supplied. Sieges are good for the army getting sieged because there is time to make plans, regroup, make better defenses, and all while not suffering too many casualties. Sieges are bad for the army getting sieged because supply routes are cut off, so food and water stocks will be worn out as the siege progresses. Siege equipment will also damage the fortification during the process of the siege. There are just a few things but there are surely more that you can think about!
