Tire Inserts for gravel. Anyone regret them?

I have Cushcore in my gravel wheels and mountain bike wheels. On the mtb, they make a big difference with handling, feel, and rim impacts. I can run really low pressure (less 4-5 psi from normal) and have incredible traction. On the gravel bike, the benefits beyond rim protection are a lot less. I run 2-3 less psi than normal but traction doesn’t really improve much.
