You know, Daredevil's "sight" relies on sound waves, right?
So, even if somehow Daredevil cannot detect Riddick's heartbeat, any sound Daredevil himself makes will, in a way similar to a bat, allow Daredevil to see Riddick.
So stealth is not happening.
As for strength, as far as I remember Riddick is clearly stronger. Physically equaling one of the raptors or whatever they are called from Pitch Black, and easily catching a full grown man jumping from ten feet above him with one arm.
As for speed, dunno, forget Daredevil things. But Daredevil beat Bullseye, who as I recall was the shit. So maybe Daredevil wins, dunno.
