I enjoy using chalkboards so much more than whiteboards. Other than the chalk dust, I just can't understand how anyone would prefer whiteboards over chalkboards.

Yeah, it's the chalk dust. It's that simple.

Also different colors on whiteboards is occasionally helpful for clarity, e.g. color-coding an equation to a line in a graph. But that's pretty minor.

we had colored chalk for that purpose in my school for math at least

I had some teachers allergic to chalk. They sent students to pound the dusters on the balcony.

You know, the worst part that makes them unbearable and a literal health hazard to use.

The fact that it's still used in many places obviously means it's not unbearable. Besides if you're bothered by the dust you can use the water cleaning methods described in this very thread. It's not perfect, but I would take a chalkboard over a whiteboard anytime.
