Brandable website names are much better than the annoying and ugly dash domains. Branding is a much better long-term goal. Depending on the types of websites you have, or services you provide, it makes a BIG difference in revenues.

Let's use finance for an example here. 

Suppose you have a website. It is mortgage.com versus find-mortgages.com. First, mortgage.com is seared into any potential customer's head. On the other hand, the other may appear as findmortgages.com to them, without the dash. This means you've just branded your competitor's domain into their head instead of your own!

On the search engines, sure, domains are important. However, they are not THE most important, if you want fluid search engine traffic. I've noticed over the last few months, search engines have been giving a lot more attention to non-dashed domains, than the dashed ones.

I'm sure other SEO experts will disagree. However, when searching for something, I generally stay away from the dashed websites. Also, from a mortgage perspective, when looking for a mortgage online, and you are willing to fill out a lot of personal information, which would feels more comfortable? Do you want mortgage.com or find-mortgages.com? I go with option A.
