Top Trees generalize Link-Cut trees:
- Support path and subtree queries
- Handle non-local tree queries
- Cluster-based decomposition
Top Trees can answer queries that neither Link-Cut nor ETT handle efficiently:
- Path + subtree combination queries
- Distance oracles
- Certain dynamic programming on trees
However, Top Trees require roughly more code than Link-Cut trees. For most competitive programming problems, Link-Cut trees or simpler structures suffice.
