VERDICT

Should I use Azul?

Better Java Performance, Superior Java Support - azul.com

Depends. Buy if you run Java at enterprise scale, face Oracle licensing costs or audit risk, and want SLA-backed support. Small teams and hobby projects should stick with free OpenJDK builds such as Temurin or Azul's own free Zulu.

Confidence

Medium. Based on 14 public sources; mostly vendor-authored pages plus community forum threads. No independent review-site ratings found.
