How does this compare with the Apex Bionic, and why is it better?
They look to be very similar with the following differences: The Mckinley is lighter (although I'm not 100% certain of this), has a performance fit, and the biggest difference is the material. The Mckinley uses recycled TNF Apex Climateblock fabric, which has a nice 4-way stretch. I hope this helps you.
From what I have researched, the weight is practically the same. As for the fabric, what makes the Apex climate block a better fabric, and is it really worth the extra cost?
