@eloy,
It's worth adding that Donnelly uses Tufo's tubeless tubular casing. I think this is fairly important, as it means that pinch-flatting is harder, harder even than tubeless (yes, you can pinch flat tubeless by ripping the casing from the impact, or burp off the casing).
I'd bet that the casing is less supple than the standard clincher for this reason. It's also a bit heavier (advertised weight only) for this reason, though if you're using a butyl inner tube, the butyl adds more weight than the difference in casings. Latex will likely be heavier, but maybe it will even out.
In terms of performance, the tubular is probably an improvement over the Tubeless Ready version as the TR probably sports the same casing, just a bit less, with two 25-50g beads added. So the tubular tire is lighter, paired to a lighter rim, and is probably harder (when glued on right) to roll.
FWIW, I've been using Tufo tubulars and now Clements (predecessor to Donnelly) for over 25 years. Excellent durability, flatting is rare, though I do add a little tubeless goo to the tires. There are more supple tires out there--Dugasts and FMO's are amazing, but the cost (not to mention the risk of flatting) is more amazing than I think my cyclocross performance is worth.
