Pound for pound, titanium IS stronger than steel. However, given a screw is a particular size, a steel screw will be stronger than a titanium screw of the same size. Therefore, given the facts, I wouldn't think titanium would be better in high stress areas than steel.
If you made a titanium screw the same length and weight as a steel screw, your titanium screw would be both stronger, and thicker than the steel screw.
About half your screws should be steel, the rest aluminum or nylon for ultimate performance. Screws holding things like body mounts and pivot balls should be steel, while the majority of the rest can be aluminum or even nylon for the ultimate in weight savings. Far too many people run aluminum screws everywhere in their car, only to see them break off in the piece they're screwed in to ending their race due to a crash or errant corner marshals foot or similar.
