It wouldn't be fair to compare AA Gill to Bill Bryson but it is interesting to contrast the writing style of An Englishman in the US and an American in England.
And perhaps I have been spoilt by Bill but AA Gill comes across as very dry and rigid in his prose with very little folksy humour.
There is absolutely nothing wrong with that but perhaps it doesn't come off the pages as well as Bill's and it feels like history lessons at times. Which I dread.
