Adding a comparison to a report is similar to which Universal Analytics feature?

In GA4, adding a comparison to a report allows you to compare different user segments or data sets side-by-side within the same report, much like how Universal Analytics' date range comparison feature enabled comparing performance over different time periods directly within a report. While Universal Analytics filters narrow down data and advanced segments create persistent user groups for analysis, neither directly mirrors the immediate, side-by-side comparison of different data sets within a single report view that GA4's comparison feature offers. Creating a separate view in Universal Analytics was for isolating data, not for direct, in-report comparisons.
