I bought ProCore when they first came out and ran that setup for many years. I also have a reasonable amount of time on Cush bikes. When I upgraded to a 29er a few months ago (Ripmo AF) I bought the Tannus Tubeless inserts through my local Trek dealer. I am in love with them, less weight than my previous inserts and significant sidewall support.
On "dry" days I've been running 22/24psi and on slower greasy/wet days I've been riding 19/21psi. I've always struggled with rolling the rear tire over when running ProCore (or no inserts) but the Tannus inserts definitely support the sidewall enough to significantly reduce that issue just like CushCore. At 21psi I can still get the the tire to roll over so I save that low pressure for slower muddy rides.
The one thing I don't know for sure yet is how the Tannus does on the front compared to ProCore/CushCore. I have a tendency to burp the front tire off the rim and ProCore nicely locked the tire on (via 80psi in the inner tire) and it remains to be seen if the Tannus puts enough pressure on the bead (Tannus isn't as tight as CushCore Pro).
My initial impressions are that Tannus is better than CushCore XC and lighter than CushCore Pro and cheaper than both. I think it's going to be a very popular option...
edit: I should add I usually run an Bontrager SE5/SE4 tire combo though I am currently running Assegai tires front and rear.
edit2: For reference on my tire pressures, I did 2 rides on my new bike without inserts at 26/28psi and put as small flat in the rim bed of the rear rim and a sidewall dent on each of them as well (I weigh 170lbs).
