Probably it is a good license, but it is rather difficult to find information about it, apart from the official site.
This licence seems still a bit short, to produce a clear legal framework.
This license seems to priori more "open" than the current license.
I think that in case of trouble "legal", it is "more easier" to assert its rights when the software/code source are under the protection of a license widely used.
The GNU GPL has produced a lot of case law from courts.
