I was going to post just this. While I'm very skeptical that either of them will become popular, dat seems to be more suited for publishing websites and sharing large files. For a website it's nice that you share the whole site and are able to update the content while keeping the link (it's possible to tell if the content has changed, but there is no version history). And dat is already my first pick whenever I need to copy large files privately over internet.

I blogged about my experience with dat a couple of months ago. Here's a link if anyone's interested. https://hannuhartikainen.fi/blog/dat-site/

Since then I've used dat for copying files a couple of times. I haven't really browsed the dat:// web and I'd guess nobody has visited my website over that protocol (but then I don't have analytics and estimate my blog to have a dozen visitors a month).
