BGP's path vector routing information includes the 'path' of ASes that are used to reach the destination, BGP has a complex path selection process. AS-path length has nothing to do with the number and or speed of the links to reach the destination and so an AS-path length of 2 can take far more time than an AS-path length of 4 because you don't know the inside topology of those ASes.
Distance vector will give you the actual number of link hops (RIP) or a metric of hops, and link speed (a simplified description of EIGRP). Distance vector does not give you information of what links you will use (the path you will take) BGP does tell you what ASes you will transit.
