both have the advanced bw mode, same size, same paper option..so for that one or the other will do.
the k3 vivid ink give subtle difference of color image that have lot of majenta like a portrait, having made some test on my epson 4800 vs a 7880, i would not say the difference is crucial.
The newer epson have the ability to print on CD, to be plug on 2 computer at once...if you dont need those extra features, and if you save money on the 2400..go for it your eye closed for sure.
