I’m currently renewing two cars. Previously I’ve just gone with whoever offers the cheapest cover and assume they’re all shithouses. Over recent years the defacto(?) ratings seem to be more and more prevalent in the selling elements with not many companies offering 5 star ratings. I’m now getting quotes for 5 star companies at around or slightly more than the cheapest quotes and I don’t know if it’s worth the extra, I’m keen to point out I don’t want to test this out for myself  

 but if an extra £20 might stand me a shit load of hassle (and time I won’t get back) should the worst happen I think I’d be inclined to pay it. 
Question is, should it ever come to it, has anyone found the 5 star companies to be any better at handling claims and giving better service compared to the less expensive ones?
