The RAC and AA both try to maintain that they are "premium" services, and charge accordingly. In days gone by , things like route planners , hotel recommendations , maps etc were pretty useful but now we have so many other sources for them, that they really only fulfil the breakdown cover for most of us.
I went with the RAC originally as they would recover a vehicle from the track after a racing accident, which the AA would not. Mine covers me and my family (of 5) in any car that we are either driving , or happen to be a passenger in. I think my premium is approx £200.
Each year they threaten me with an increase to about £280 for no more cover, I promptly put my details into the AA website and obtain their quote (which is usually lower for a newbie as they want to lure you into their web) I go back to the RAC with this and they match it . It is really just a game now.
Good luck
