Bora Care is a wood preservative that kills termites, wood destroying organisms and also fungi. It contains a form of Boric Acid known as Disodium Octaborate Tetrahydrate. It also contains glycol which is a penetrate and helps the DOT to penetrate the wood. It will penetrate "bare unfinished wood" up to about 2".
Timbor is powdered "DOT" and does not contain glycol, therefore its penetrating abilities are limited. Usually about 1/4" or less, depending on how much the wood actually absorbs.
Both products will not penetrate stain, varnish, paint, lacquer, etc. If the wood is not bare and has any of these finishes, the finish has to be sanded and removed before Bora Care or Timbor is applied.
Application of either product to a sealed finish will not provide any penetration into the wood, and is similar to spraying water on wax paper. It simply runs off.

Bora Care is usually the best product to use in almost every situation. I personally do not like Timbor for wood treatment in a water base solution.
Hope this helps.
