There are only so many ways to determine paths, e.g.:
- by the structure of the address itself
- by flooding, at least until you cache a path
- by knowing what flooding would have accomplished, e.g., by ‘global knowledge’ of the network topology

We use all three in the Internet (longest prefix, ARP/LISP, and RIP/OSPF, respectively).

“Better” is relative; structure is more efficient and scalable but harder to manage, flooding is least efficient and scalable but requires no management, and global knowledge is a bit of a balance between the two.

Or is there some other “better” you’re imagining?
