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 are significantly more complex to implement. For most competitive programming problems, Link-Cut trees or simpler structures suffice.
