Here'are two sentences:
- It's not beer WHICH destroys people, it's beer WHICH does it to them.
- It's not beer THAT destroys people, it's beer THAT does it to them.
Pretty weird sentences but they are qoutes from a Russian movie translated into English :)
Which sentence sound more natural? To me both are okay as both, 'that' and 'which', may introduce a restrictive relative clause.
Here's what Oxford says: http://www.oxforddictionaries.com/words/that-or-which
