I'm a big Rizzini fan, I've got a Roundbody EM 28ga that I love. But one thing to know about the 16ga BR110 is that it's built on the 12ga frame. The other models like the Aurum, Artemis, Roundbody, etc are built on a 16ga frame. These models are quite a bit pricier, no surprise there.
I like Franchi's too, and I have seen a couple of the Instinct Sideplate models in Scheel's and they look great. I'm 99% sure they're built on a 16ga frame.
I'd like to run across a FAIR SLX600 in a shop someday so I could hold it and see if it fits me. There's a nice one on gunbroker right now, and they run a little under $2k.
