I'm running Tannus Flatfree tires on my winter commuter. Some notes are in this thread.

They're a major pain to install, at least the first couple one mounts. I think they are a little slippery when wet. Also slightly higher rolling resistance (not the biggest issue for a commuter). I've now got a couple thousand trouble-free miles, and am looking forward to many more flat-free miles.

However, summer riding is much less stressful on the tires, so I have pneumatic tires on all the other bikes I tend to ride in the sunshine.

I did pretty well with my Origin8 Elimin8er tires. A couple of incidents, but nothing major. I ground them down way past what should have been the wear mark, and they kept going.

I now have a Gator Harshell on the rear of my road bike and a GP 4 Seasons on the front. I did rip a hole in the sidewall of the hardshell which is now booted and patched. That is one of the potential weaknesses of the tire. But the road crack I did it in was pretty bad.
