What is the best quantum chip?

Could you please elaborate on what criteria you're considering when asking about the "best" quantum chip? Is it based on the number of qubits, coherence time, gate fidelity, programmability, or perhaps a combination of these factors? Additionally, are you looking for a chip specifically designed for a certain application, such as quantum simulation, optimization, or cryptography? Understanding your specific requirements will help me provide a more accurate and relevant answer.
