I use GraalVM as my standard non-native JDK (OpenJDK replacement) and I'd say the performance is somewhat better.

There are a lot of non-biased benchmarks you can find online, most of them showing that Graal (both CE/EE, though particularly EE) are more performant than OpenJDK.

You then also have the option to compile to native, or to embed/run code in other languages baked in.

It's a no-lose scenario IMO.

Are there no downsides?

It usually needs a bit longer warmup period in my experience. But for long-running processes it can be ideal, Twitter for example uses it for quite some time in production.

Also, not every GC is available, or only in the enterprise version.
