This is nowhere near as convenient to use as the Michelin. This is despite the larger scale - or perhaps because of it. The large scale and smaller pages mean that you can't easily see your route across the country. The AA atlas shows more minor roads than the Michelin, but at 3km:1cm (as opposed to 4km:1cm) it's still much too small scale for the sort of touring that the OS does so well in the UK - if you're doing very small villages you'll need a satnav whichever of these you buy. For route planning - getting from one town to another - the Michelin is incomparably easier. The AA map is also wildly out of date - I bought it 10/09 to replace my 2006 Michelin, but very quickly put the AA in the boot and reverted to the Michelin for the whole 2000 miles we drove - it's almost as up to date. Next year I'll buy the 2010 Michelin - the AA is going to the Christmas village bazaar!
