We're going through this exact problem right now. My partner and I are working on a new service for photographers and videographers, http://lazyscout.com http://lazyscout.com. The question came up about whether to have the Like button work for the site, or for the Facebook page for LazyScout. We discussed it briefly and decided to have it focus on the Facebook page for the time being. Our reasoning is that since we're trying to bootstrap awareness of the site (currently a landing page with interested signup form), our Facebook page will be a more useful marketing tool for now. Since we get no SEO benefit of people "Liking" our domain, getting as many folks as possible to like the page helps us inside the FB ecosystem. We need 25 Likes to get a public facing page, for example. Now at some point in the future, we will revisit this decision and decide if its worth switching the Like button back to the domain to direct traffic there. Its all a balance of how you're trying to leverage your zero marketing dollars, like us.
