As of Java 24 (Java 25 being an LTS) I'd say they are equivalent. You can use a virtual thread just like you use a regular thread and there's basically no handicaps or gotchas. In Java 21, when they were released, there is a gotcha that the pretty normal use of the `synchronized` keyword would pin a "carrier thread" which ends up blocking all virtual threads from running on that carrier thread.

Pinning can still happen in some much more rare cases, same with go. For example, FFI.

The memory usage, performance, etc are all go like. You can spawn millions of virtual threads with hardly and memory requirements and without overburdening the OS with context switches. The JVM also enjoys faster GC performance with virtual threads.
