Would employers prefer A levels or BTEC National Diploma if you don't plan on going to university?

I am applying for colleges, and one of the colleges I am looking at offers the subject most crucial to my career choice as a BTEC but not as an A level. I was wondering if it would be better to study it as a BTEC, or take it as an A level elsewhere. Would the additional subjects from the A level be preferable to the more in depth aspect of the BTEC?
