drywall (not moisture resistant) in the basement?
green board (moisture resistant) is better.

Mold will grow just fine on either one, so I don't think you're
referring to that. If the basement has such significant moisture
problems that greenboard might be indicated, it would be far
preferable to deal with the moisture problem before finishing the
basement.

blueboard with plaster would have been the best choice and could have
been completed in a few hours.

1400 SF of skimcoat plaster in a few hours? Not even close unless you
have a small army on hand. If it were that fast, no one would use
drywall, tape and spackle.

1400 SF of skimcoat plaster would be much slower than 3 or 4 hundred
linear feet of tapered edge taping and spackling, and a bit of bead
work. If the OP's contractor isn't resistant to using setting type
compound they could skip all of the drying time.
