which one I prefer. Actually I like both.
But specifically, for the sake of studying Paris and its historical geography, I like the the first one better. Just for the fact that the chapter was read by a French or a lady with french accent. This element is important in making audience believe that everything is authentic when the account on Paris proceeds.
For the purpose of learning English, I prefer the second one, which demonstrates the standard British accent, the beautiful flow and the elegant intonation. BTW, the French accent in the first audio is actually not a flaw of the product. It creates a luring texture for the audio, like a special flavor added to a fancy wine that passes to you a 3-D pleasure.
