I will stick with the Sun JVM...

But the IBM SDK does have some advantages beyond speed. The use and expansion of PermGenSpace is much better than in the Sun SDK or GCJ. This is not a bog deal for client apps, but heavy lifting J2EE servers, especially portal servers, can really cause the Sun JDK heartburn.

Have a look at this paper I've wrote comparing the Sun vs IBM JVM GC. It turns out that memory performance depends mostly on the application and not so much on the VM.

And Sun's JVM has a big advantage over IBM, at least on Solaris: DTrace providers
