The collectors edition is clearly better than the original edition, containing such gems as a sneak preview of Togepi. I found this book quite useful, but I thought that it could be improved in the following ways: 1. by telling you the level in which the Pokemon learns his attacks 2. by telling you more about how to beat the gym leaders. 3. by telling you which Pokemon can be found in which colour game. Otherwise I thought it was very good as it gives a clear description of each Pokemon (even MEW) and tells you how to pronounce their names. The only thing I found a little annoying was the way that it addresses you as a Pokemon Trainer inside the story - but that's my personal opinion! Otherwise it's great and worth the price.
