I’ve heard both Raven & Kuzma.
They are both great- however I prefer the Kuzma by some margin - the 4point11 arm is a superb arm, transparent and very quick.Set up and on the fly VTA on the Kuzma is super easy due to the great design.
I think the Kuzma combo will be a bigger upgrade over the Sota than the Raven - I use to own a Sota Star and know it well.
