Well, I always travel with Backpacker (+ another in addition), it lacks a few pictures for fun but it's always interesting, well documented, regularly updated (much less surprises on erroneous addresses with other guides), there is always a certain objectivity in the comments, good restaus addresses (again we are rarely disappointed because we expected exactly as advertised, and I discovered great affordable restaurants all over the world through Routard). In addition, it gives us the "survival kit" for each country, and it's really often helpful.
