The thin layer of moisture/rust, I can deal with because it usually goes away after a few stops anyway.

I think the beneifts of discs outweight the drums in my opinion. I will only take a car with drum brakes if it's given to me or if the car is a huge steal compared to one with disc brakes. but aside from that, I probably won't buy another car again with rear drum brakes, ABS or not.
Discs get rusty too. The pads scrape off the rust when you drive the car; same thing happens with the drums.

Brake dust doesn't particularly get "trapped" in the drums. They are not fully sealed. There is a backing plate with a gap around the circumference of the drum. If you've ever actually replaced drum brakes, you won't find that two shoes' worth of dust falls out when you pull off the drums. Notice how your rear wheels get caked in brake dust just like the front ones (though usually to a lesser extent than the fronts because of brake bias and the drums spitting out most of the dust away from the outer side of the wheels), so it's obviously leaving the drums.

Which ones are Better?
Disc brakes operate better than drum brakes because of the difference in dissipation of heat in both systems. While drum brakes get overheated due to the heat trapped inside the drum, the rotor cools faster and offers better braking ability. Today most cars have a combination of both brakes in their functioning. Front wheels are fitted with disc brakes and rear wheels are fitted with drum brakes. There are high-end cars that come with disc brakes fitted in all wheels. Drum brakes are cheaper than disc brakes. A combination of the two braking system helps in keeping the price of a car to be reasonable, while offering adequate braking ability. If you opt for disk brakes, there is a lesser risk of frequent problems.

The choice in fact is quite simple and opting for disc brakes is always the better decision as they offer better service in a wide range of driving conditions and also last longer.
Much of that excerpt is pretty bogus (...aside from the fact that they didn't even proofread it, which makes it even less credible). "Lesser risk of freqent problems"? Based on what? What problems, exactly? "Opting for disc brakes is always the better decision" is a fabrication as well.

Fortunately I have steel wheels with plastic covers so I don't have to worry about the brakes looking cheap. :P

I'm not a huge fan of drum brakes myself, but most of the arguments people are making here in favor of discs are questionable at best. If you prefer the aesthetics, fine. If you race autocross, or you really want to do your own brake work and can't stand drums, fine. But it's a waste of money beyond that. Again, it would be better spent on tires.
