Each figure is the marketplace's own and is never added up across marketplaces. A marketplace that publishes no figure shows none: no number is not zero.

Lines where the two differ have a tinted background and bold values. Where the data itself says which value is better (more marketplaces, a larger figure of the same marketplace, a fresher release, a verified mark on a marketplace that lists both), the better one is also marked green with ▲ and the worse one red with ▼. Where it runs, the transport, the tools, the settings, hooks, the bundle's parts, the licence and the week's changes are marked only as different: more or fewer is not better in itself.

Tools each declares
The marketplaces of JavaLens publish no list of tools, so we do not compare tools.
Settings each asks for
Only JetBrains asks for
IDE_PORT
Only JavaLens asks for
JAVALENS_LOG_LEVELJAVALENS_TIMEOUT_SECONDSJAVA_PROJECT_PATH
Settings as each marketplace publishes them. Asking for fewer is not better in itself.
