I love this stuff, and while I consider myself informed, i'm not an expert. However, I've bantered a bit with Scylla's CTO and others about how I would regularly run into issues with Scylla because they didn't use TPC, and I'd see hot keys that would suffer performance because they only let one core manager a subset of keys... So, while I can't make an authoritative statement, I think TPC is better overall...
