I can’t add much as I am new to tubeless. I have been running road tubeless (Flo rims) for about 18 months now. I have only used Stan’s Race. It has fixed a number of punctures now. It is thick and can be hard to work with (having to pull a edge of the tyre off to pour it in) but it does the job.
I will say, I’ll never go back to a tubed setup.
