What is the most functional and ready-to-use SWT API in Scala?

Is there a Scala SWT wrapper/API that has the most features and is most ready to be used? I see a couple what appear to be informal wrappers but can't tell if they're m开发者_StackOverflowaintained. Also, one or two I see on multiple places and I'm not sure where the canonical place for them.

I've been using Dave Orme's XScalaWT with my own additions for JFace viewers for a while, and I find it great. Be sure to read the very interesting introductory blog post.

I'm also aware of SSWT but have no experience using it. I believe XSWT is more mature.
