Greeks and Macedonias with their Phalanx units and ofc Egyptians with their Chariots.
Greeks because their hoplites are a godtier unit with no direct counter because of the speed to close gaps on their otherwise natural counters of archers.

Greek hoplites are still easily countered by Composite bowmen and chariot archers in the bronze age. And in the iron age they get destroyed by horse archers even when fully upgraded. Not to mention they are expensive. You would be better off making siege as greek. Hoplites would be better if they would be supported by anti archery units like slingers which should really get a bonze age upgrade, but I doubt this will happen.
