• Protocol coverage no modern tool matches — JDBC, JMS, LDAP, mainframe-adjacent protocols.
• GUI test-plan building is accessible to testers who do not code.
• Enormous body of documentation, plugins and available expertise.

• Handles enterprise protocols such as SAP GUI and Citrix that open-source tools cannot.
• APM correlation makes root-cause analysis much faster than latency graphs alone.
• Both GUI design and as-code authoring, so mixed-skill teams can share a suite.

• Thread-per-user model is memory-hungry; high load needs a cluster where k6 needs one box.
• JMX test plans are XML that merges terribly in version control.
• The GUI must not be used for actual load generation, which trips up nearly every beginner.

• Expensive, with a procurement-scale sales process.
• Overkill for a straightforward web or API workload.
• Proprietary scripts do not port to other tools.

Enterprise performance teams needing protocol breadth and a GUI-based workflow.

Large enterprises performance-testing SAP, Citrix or Oracle estates.
