Well... It's such a close call between them both, but I'd go for the Radeon X1300.
Mind you, that's just a personal preference I have for ATI/AMD devices. The reality of the matter is that they're both almost evenly matched in their performance, in some cases the 7300 would be superior, in others the X1300 would be.
X1300 would be superior to the 7300L
