I'm seeing a lot of "I haven't used it but..." in this thread. As someone who's actually been using Sails consistently since v0.10, I can easily say that it's without a doubt my favorite node framework.

I use it because I can go from idea to functional prototype in just a few hours. I don't need to spend a bunch of time deciding how to best structure my projects because it's obvious where things go.

When I have to work on a product that wasn't built on Sails, it's either a complete mess or it's clean but only because they've burned a ton of development time creating many of the same abstractions that Sails comes with out of the box.

I'll admit, the ORM hasn't always been great when you need to integrate with an existing data store. It's absolutely perfect for simple CRUD apps though and you always have the option to run native queries.

The only other semi-valid complaint I'm seeing is that the docs are bad. Well, they've been bad in the past. The new docs for v1 are loads better. I've referenced them quite a bit over the last few months.

I just launched my second product this year built on Sails and I'll soon start my third. The new features in v1 are absolutely worth giving it a shot if you haven't already.
