Absent disassembly and direct comparison between a DGX Spark and a Dell GB10, I don't think there's sufficient evidence to say what is meaningfully different between these devices (beyond the obvious of the power LED). Anything over 240W is beyond the USB-C EPR spec, and while Dell does have a question ably-compliant USB-C 280W supply, you'd have to compare actual power consumption to see if the Dell supply is actually providing more power. I suspect any other minor differences in experience/performance are more explainable as the consequences on increasing maturity of the DGX software stack than anything unique to the Dell version; particularly any comparisons to very early DGX Spark behavior need to keep in mind that the software and firmware have seen a number of updates.
Comparing notes with Wendell from Level1Techs, the ASUS and Dell GB10 boxes were both able to sustain better performance due to their better thermal management. That's a fairly significant improvement. The Spark's crusted gold facade seems more form over function.
