Falcons WR or RB

I’m worried for week 12 since I have Gurley and Cooks.

My RBs Zeke, Gurley, Mitchel. WRs Michael Thomas, Keenan Allen, Brandon Cooks.

Someone wants to trade me Ridley for Coleman both ATL. They play Saints that week, who is my better matchup? Should I make the trade? WR or RB for this game

Just to Add I just picked up Dez Bryant who plays Atlanta as well. But already playing Thomas for sure.
