Large wheels and large quality tires at lower pressure will deal with potholes and will be lighter and faster.
Suspension adds maintenance, pedal bob, weight etc. Outside MTB, I don't see that being better overall.
My rigid bike with 29x2.15" front and carbon fork deals with all roads comfortably and is light and quick.
Good suspension needs maintenances ever 100 hours. And cheap suspension is just a boat anchor.
