You're right about the two different types of sweat glands.

And just to finesse what you're saying here:

> The smell is related to bacterial activity in the "apocrine sweat". Armpits don't smell because they sweat more; they smell because it's a different kind of sweat.

Even the sweat from the apocrine glands doesn't smell when it's produced. But because it is much richer in nutrients than the sweat produced from the eccrine glands (which is 99% water and the last 1% mainly being salts), it is a fertile feeding ground for bacteria. And it's the waste excreted by the bacteria feeding on your appocrine sweat that smells bad, not the sweat itself.
