Sei vs 
Sui
Two 2023-era chains promising speed through parallel execution, from different technical families. Sui uses the Move language and an object-centric model inherited from the Diem lineage. Sei is EVM-compatible, which lowers the barrier for Ethereum developers to port applications across. Familiar tooling against a purpose-built model is the real choice underneath both pitches.
