Digital Frame or Standard Mat?

I could use your help/advice on a project.

I am having my first exhibit of my travel work later this year in NYC. Which of these printing options do you prefer: Printing the image without (top) or with (bottom) a digital frame?

Printing the image with the digital frame would let me sign the print itself.

If I print the image w/out the digital frame, I'd print full frame on the paper and sign the white mat.

Also, price not being considered, would you be more likely to buy a 24x36-inch print or a 24x16-inch print?

Your help sure would be appreciated.

Thank you!
