In the context of both the peoplecode. The record level peoplecode will be fire first then component level peoplecode.one record level peoplecode might be associated with several different Components so that It is posiible to trigger the same Record PeopleCode from several components while the component level code is associated with a unique component.

record level peoplecode is associated with number of component but

component level peoplecode is associated with in the same same component.

Record level people code will be attached to the record and anywhere we use the record the peoplecode with it will be fired.

Component level peoplecode will be attached to the component and not to the record. So even if we reuse the record we will not have the peoplecode attached to it. Hence writing peoplecode in component level is more efficient.
