I've moved to OPNsense from pfSense. The OPNsense team has made many worthwhile improvements (improved GUI, numerous security updates, fixed, and choices) to the project and are much more responsive. There have been some bugs, which is expected with a newish project, that have been quickly fixed. At the moment, I would recommend this as the SOHO/SMB FW distribution of choice, but would recommend a commercial solution in an enterprise environment.

Far better design than pfSense, and running on a more recent, more standard, better hardened FreeBSD. But there are major bugs in the more complex functions, such as handling MultiWAN and CARP VIP assignments, which when brought to the attention of the developers -- who in general are nice guys -- are beyond their abilities to comprehend or fix, perhaps because inherited from the poor coding practices in the remaining pfSense codebase.
If you have a simple home router setup, this is the bees knees. For sophisticated business environments, the concepts here are good, but the execution is inadequate.
Many great improvements when comparing it to pfSense. Especially the GUI is way more polished. Under the hood the changes are significant too, a lot of ancient code has been rewritten from scratch. The developers are kind and respectful, in my very own experience they take every idea/bug report/suggestion serious.

Many issues with DNS. Installation takes forever and is very convoluted. Not impressed with the GUI. I guess that is a matter of taste. There other firewalls I would use before choosing this one.
