Is there any comparison with MassTransit.NewId?

I benchmarked creating a couple of different unique identifiers as I was also curious:

BenchmarkDotNet v0.13.12, Windows 11 (10.0.22631.3880/23H2/2023Update/SunValley3)
13th Gen Intel Core i7-13700KF, 1 CPU, 24 logical and 16 physical cores
.NET SDK 9.0.100-preview.6.24328.19
  [Host]     : .NET 9.0.0 (9.0.24.32707), X64 RyuJIT AVX2
  DefaultJob : .NET 9.0.0 (9.0.24.32707), X64 RyuJIT AVX2
