Well, attack planes always get less love than fighters. But A-4 is wonderful, looks (mostly) good, said to fly well, was cheap, carried a big load for such a small aircraft. Rightfully called a hot-rod. But, I don't like the look of the early versions, and I don't like what Israel did (see picture). That's just ugly. It isn't really big, fast, fascinating or powerful. That's why it's not in my top 5, but if I would have an aircraft museum, I'd definately get one and give it a good spot...
