Micro benchmarks are written to avoid creating garbage since code is faster that way. C# wins these comparisons easily.

I haven't found a comparison of JVM vs CLR GC but I know the .NET team has intended to introduce a ZGC style collector for a while.

The need is not as severe in CLR because it produces less garbage.

But CLR stop the world pauses are long and it's definitely a problem for some uses cases. Many companies focus on their P99 latency these days and a 1 second GC pause will ruin those metrics. And stuff like HFT just can't be done in C# without turning GC off
