Rival is stiffer and cheaper...Red is lighter.

Rival is among the stiffest cranks on the market regardless of price point or weight or anything. It's just stiff! I had Rival on my Specialized Roubaix Expert. It was fine, it worked great. I got Red...and it also works fine, it's great.

Unless you're an absolutel BEAST pushing a bazillion watts on a climb or sprint in the pro peloton, you won't noticed Red being any less stiff than Rival. Similarly, while riding, most people can't really tell that Red is a lighter crankset than Rival either.

If money is in good supply, just get Red...it's lighter, very stiff, and has bling factor. It might make you faster just via the psychological effect of knowing you have one of the stiffest light weight cranks.
