The difference is that it will be one less script to run you will get the modules automatically inserted into the root file system, and the result will be in the binaries directory. With the Advanced Kernel Configuration, you should be able to build basically any kernel version, and you are able to apply patches much more freely than before. If you use the same version as the kernel headers, then your kernel version choice is rather limited, and if you choose to go with the latest, then the kernel version will be updated once or twice a month.
