Will pi bonds be stronger than sigma bonds? Or is there a way to tell whether there is a strength difference?

Sigma bonds are actually stronger than pi bonds. Sigma bonds have more of a linear overlap whereas pi bonds have a "parallel" overlap. The electrons are held more tightly to the nuclei of sigma bonds than pi bonds. Image

As mentioned in the other post, a sigma bond is stronger than a pi bond. Then, the reason why a double bond is stronger than a single bond is because it consists of both a sigma and pi bond while the single bond consists of only a sigma bond.
