Who makes the best ignition wire set?

Getting closer to the answer for this but in reality it's "no one." Most US produced wire sets (at the retail customer's request) have degraded several components to reduce cost. Think galvanized terminals instead of stainless steel, lower cost (less durable and/or heat tolerant) polymer compounds, and less expensive alloys for spiral conductor material. A little sad considering this is the same place NASCAR wires come out of (for some, not all).

I'll be getting a US made Standard Motor Products wire set but it's components will be a mix from several different customer spec parts.

There you have it.
