Broadcom vs Mellanox based platforms

Hello I’m asked to evaluate switching platforms that has different forwarding chips but the same OS. Assuming these vendors give the same SDK and similar documentation/support, then what would be comparison points to consider, other than the obvious (price, features, bps, pps). I’m thinking, how do i validate their claims about capability to do leaf/spine arch, ToR/Gateways, telemetry, serviceability, facilities to troubleshoot packet drops or FIB programming misses, hidden tools...etc It would be great if anyonw can give some thoughts around it, specially if you have tried one or both. Thanks Kim
