haseebhm on "[Plugin: WordPress SEO by Yoast] Breadcrumbs: My theme already supports"

I'm using the latest of version of the plugin with a theme from TieLabs.

My theme already supports breadcrumbs. Do I still need to activate the breadcrumbs feature of the plugin and disable my theme breadcrumbs ? Which option is better from SEO perspective ?
