Query: Not the best investment

At the moment, there are two main contenders on the market with comparable books on West Africa: Rough Guide and Lonely Planet. Neither is perfect.Rough Guide may feel a bit more professionally-made, and has been made on a bigger budget too, but it suffers from terminally boring writing style.I said this before and I`ll say it again: if people who write guidance for your tax returns were to write guidebooks they would probably come up with similarly uninspired language.The book does not offer the same level of self-righteous (and often annoying) rhetoric about evils of capitalism as Lonely Planet. I find this aspect commendable: some of us want the travel guide to give us facts and not explanations for whom to vote and what to think.However, on balance, I have to admit that Lonely Planet is better resarched and more accurate, and also less bulky. If you have plenty of luggage allowance and money's no object, buy both, otherwise, stick with Lonely Planet.
