Gonna chime in here with my experience.
I'm definitely in the "run lighter casing tires with inserts" camp. Before I started using inserts, I was pretty much relegated to DH casing tires - for the sidewall strength, and for the snakebite resistance against rim strikes. With inserts I can get away with EXO sidewalls, and my rims don't see rock strikes anymore. I personally wouldn't go with an insert that didn't provide good sidewall support, meaning I don't think the Rimpact would work for me.
For the record, I'm currently running Tannus Tubeless Armour inserts with EXO+ casings (Assegai MaxxGrip-21psi up front, DHR2 MaxxTerra-22psi in back). This setup is as close to perfect as I've found to my riding style. The EXO+ and Tannus inserts probably weigh the same as DH casings alone.
My take on inserts is they are one of those things you didn't realize you needed until you've tried the right ones. I can't imagine riding without them now.
