Comparison of prints of Epson R3000 with Epson 3880. C/c??

I own a fabulous 3880 and wonder if there is any image quality comparison between the two printers. I apologize if this question has been explored before, but I couldn't find an answer to the question. Any remarks about 2 picoliter vs/ 3.5 picoliter size droplets? Thank you.
