Differences between brecia and conglomerate

Based on the definitions of these two rocks, which of these two types contains clasts that have been transported a longer distance?

Conglomerate, because the clasts are more rounded and eroded by mechanical and chemical weathering during transport before lithification than breccia is.

"...American HeritageScience Dictionary
breccia (brěch'ē-ə, brěch'ə, brěsh'-) Pronunciation Key
A rock composed of angular fragments embedded in a fine-grained matrix. Breccias form from explosive volcanic ejections, the compaction of talus, or plate tectonic processes. Breccias are different from conglomerates in that the fragments they contain are angular instead of rounded.

Breccia clasts are more angular which means that they haven't been transported much and that they are close to their source rock.
Conglomerate clasts are more rounded because they have been transported a longer distance so their orignal shapes have been altered from angular grains to more rounded.
Anything that has been transported by a transporting agent such wind/water, they tend to have more roundish shapes than angular.
