All options depend on network bandwith.

If you want something elegant and semi-transparent, consider dblink IF your nodes are LAN connected. DBLink over WAN is a nightmare...

Options 1 and 2 may use offline compression, in order to reduce sending time.

Option 1 may be benefited with parallel load/multiple DB writers, direct-path loading which gives less disk usage (if you compress receiving tables), thus lowering IO when executing EXCHANGE PARTITION.

Option 2 seems like 'almost' transparent, kind of plug and play... I've not tested it.
