I did that road a couple of weeks ago and, although it is really good, SWMBO made me keep stopping for fecking pictures and to buy fresh cherries from roadside stalls. After half a kilo of cherries I shat for England, kid you not. To say it is the best is stretching it a bit although we are all entitled to our opinion. I think the roads to the East on the Spanish border are as good, over the mountain tops and the road up to Torre was easily equal to it and a lot cooler. Better road to be found just North of Almeria but I can't for the life of me remember what it is called, I will try to find one of those stitched together pictures I took and post it.
