Mold Resistant Drywall or Greenboard?
Is the "Mold Resistant(retardent) Drywall sold at the big box stores the same or similar thing as "greenboard"? Which would you use in a bathroom?

You can use either one they are basically the same.

Just do not use it to lay tile over in the shower or tub area.

Two different beasts... Mold Resistant; 1/2" thick board, ceiling framing only at 16"o.c., never 24". 5/8" will go 24". with a water-based finish.
Green board, 1/2"; ceiling framing only at 12"o.c., need 5/8" for 16"o.c. 24"o.c.--- use another product. I'd use lightweight 1/2" spans (24"o.c.) equal to 5/8" for anti-sag, and insulation weight loaded above (2.2#).

Not all greenboard is mold resistant. Moisture resistance and mold resistance are two different things. Ask for a "cut sheet" where you buy it and read the specs. Mold resistant drywall is typically moisture resistant by nature, but not the other way around.

I've removed a lot of greenboard that looked like cottage cheese after some wary of a vapor barrier/retarder in wet areas (or dry, IMO);

It is my understanding they are doing away with the greenboard. I guess phasing out would be a better term. So what is out there now is just the remaining stock they are getting rid of.
