Inspect differences in individual files or entire folders, or compare changes when multiple versions are involved. Binary comparison and folder comparison address different review needs; three-way merge and merge conflict tools are relevant when edits need reconciling. Version-control support and supported platforms can help you gauge fit with your workflow. Also compare free plan availability and the Paid from amount. Diffract, Meld, and Diffchecker appear first in the ranking, followed by WinMerge and SmartSynchronize. Use the listed comparison and merge capabilities to focus on the kind of review you do, and check platform support and pricing alongside them.
