From a security standpoint they are equivalent in Oracle except with respect to the fact that procedures can be wrapped. But I strongly favor procedures inside of packages because they provide far greater flexibility, are far more robust, and are definitely easier to debug.

There is little more frustrating in any environment than triggers setting of triggers setting of triggers when it comes time to test. All of which consist of activities that could easily be written into a single package.
