Which Should You Choose?
For applications where sub-100ms latency is required, American Express is the stronger choice. For deployments with higher latency tolerance, either provider is suitable based on this data. Multi-week or multi-month monitoring is recommended for production decisions, as single-week data cannot establish long-term reliability patterns.
