Whether Sui can compete with Aptos is unclear. The first one is still in the test phase, while the second one is already showing good growth.

Both Aptos and Sui use Move, a Rust-based programming language, for parallel execution on the blockchain, but Sui has a slightly version of it than Aptos.It is still too early to say which one you should be more bullish on. Both projects have been developing rapidly and have done an excellent job of optimizing its current design. But whatever the case is, Move technology is most likely here to stay as it shows a lot of promise in blockchain scalability and security.
