I think it's immediately obvious that these are totally different switch than Zealios. To me Zealios are a Cherry-style tactile with a bump along a linear length, whereas Royals are a snap from the very top to the very bottom.
These switches feel nothing like other cherry mx based switches. They feel more like an extreme rubber dome or alps, but with more springiness after the tactile event. Most cherry mx based switches feel like linears with a bump overlapped, and some people like that, but these are different.
The closest switch that feels anything like these are clears, due to the remaining springiness after actuation, but the tactility is FAR stronger.
They remind me most of rubber domes with extreme tactility, like BTC dome with slider.
I personally don't mind the eventual ticking the switches will probably develop. The only other switch I have that shares this problem are my matias tactile grey switches, and coincidentally, the two switches feel similarly as well. Better in fact, because matias switches have a second tactile bump which bothers me.
Edit: I stuck my ear to my board and my A and S key are starting to click.
