Known a few people with rotary engines
They are better, but I know they cost more upfront, and I'm fairly certain maintenance becomes pretty expensive.
But if you want a rotary engine, there's a couple options.
Mazada RX8 is the most common I think in America, just good luck finding a non dealer that will work on one.
That's not what the post is about, it's about rotary valves. I'd never heard of them before watching the video, but it sounds like they don't exist in any production cars.
Rotary valves are more present in the musical instrument world, where they are used on French horns, some trombones, and some tubas.
On the topic of unconventional valves in automotive engines, I'd recommend taking a look at Koenigsegg's Freevalve technology.
