Not sure if you're suggesting I leave because I'm not happy, or if you think nas4free is better?
I've not played with FreeNAS 8.x much. I upgraded a secondary NAS a couple of months ago to 8.2. It's been rock solid. Even Firefly has been rock solid and I could never keep it running on .7. So there are plusses. FreeNAS 8.x seems to be more popular than nas4free. Though nas4free is already running FreeBSD 9.x.
So I'm thinking I'll stay with FreeNAS, but that doesn't mean I won't ask for features that I miss to be reimplemented.
