Totally false choice. As a Sarah Stegall says in her reviews, the Chuck writers
grok geeks (or more properly, nerds). I got into TBBT because of Lubos Motl, a Czech physicist who spent some time at Harvard, who pointed out on his weblog (
http://motls.blogspot.com/) that the physics in jokes in TBBT is always right, which is a very neat trick. IT Geeks with a Physics background have no choice - they have to love both shows.
Let's just say that I recognise the types in both shows, though my Physics days ended before the 80s, and I've never had to herd any cats as awful as Jeff, Lester or Morgan.
