Depends on what you want to use it for! LP is basically a quick overview if your a dumb US/Aussie college student whose idea of travelling is drinking, laughing at different cultures and generally only up for 'on the beaten track' stuff. Rough guideis a slightly more in depth version aimed at the same crowd when they hit 30 something. Have only used one DK eyewitness guide, in Bulgaria, not that bad, but still pretty low brow, main stream stuff, limited detail but at least mentions a bit more. Out of them all, the Bradt guides are generally the best, but its very author dependant as a free rein seems to be given, for a bit more in depth views on out of the way places. Problem is Bradt is often crap for hotels and food, usually way out of date. They recommend a semi derelict hotel here and there!! And I once decided to look for a restaurant in Bosnia, in Foca IIRC that was actually a really seedy den, and I've been in some rough places in my time but this was the pits............ and they didn't do food at all. Best bet I think is Bradt for sights and culture and really any of the rest, just the most recently published for lodgings and food if you like help with that side of things. But look on Amazon and read the reviews first because there are some totally duff guides for some countries.
