Smart EQ has a huge latency as well, so I'm mainly using it on the mix buss at moment. I have Neutron as well. In comparing the 2 on mix buss, Smart EQ seems to come up with much better sounding EQ curves.
In regards to Neutron, I can't really use it on individual tracks til I upgrade to 64 bit PTHD. But I transfer the EQ settings it comes up with to another EQ I can use, like brainworx V3 mix EQ. I find neutron can give you a very good starting point that you can tweak further as needed.
