Evaluating 2 WP themes for Speed

Hey guys,

Very quick question here. I currently have a WP site on WP Engine + CDN + CloudFlare that’s using Hot Topix Theme, but the theme isn’t really optimized for speed.

I was considering another magazine-based theme: Fearless WP Theme, which was advised by a few as a slightly faster alternative. But is it really?

I tried to analyze their code myself, but everything looks pretty similar to me. Can anybody give advice on which ones seems to be lighter and quicker in terms of speed? And is it a significant different? I would greatly appreciate it!

Thank you!
