I think you misunderstood the point I was trying to make.
Sure, there are good GCs out there, but good GCs are harder than many GC proponents make out.
Take the top 100 most heavily used applications or platforms that rely on garbage collection. What fraction of them actually use decent GC implementations?
Also, you seemingly misread my other point about dynamic language runtimes, I wasn't comparing them to JVMs, I was comparing them to compiled code written in lower level systems languages (like C/C++). V8 may be fast, but it's not as fast as compiled code, yet. There's still a huge gap between theory and practice there.
