1)You would need lessnetwork bandwidth with shareplex than you would for transporting archive logs. about 1/3 rd ofwhat you would need for physical stdby.
2) CPU burden would be 'little' I guess.
3) Shareplex replication allows you to have the table available for read on the target. (even update

spend your money elsewhere.
Physical standby and shareplex can operate on
archivelogs, thus they can do their jobs without any additional burden to source

archivelog's processing on target or some staging server.
