Why each option
To determine if creating an index significantly improved report performance, Live Query Statistics provides real-time, visual feedback on query execution.
SQL Server Profiler captures event data but does not offer the real-time, graphical query plan visualization needed for immediate performance assessment like Live Query Statistics.
Query Store collects historical query execution data for long-term analysis and trend identification, rather than real-time, in-progress query performance assessment.
Database Engine Tuning Advisor is a recommendation tool for suggesting performance improvements, not a monitoring tool for assessing the impact of implemented changes.
Live Query Statistics provides real-time insights into the execution plan of a running query, allowing you to visually observe the impact of the new index on operator progress, row counts, and elapsed time as the query executes.
