I completely agree. You will find most of the same information on cisco's
website as well. It is also touched on in Routing/TCP-IP vol 1.

While this is all fine going out the broadcast media (though personally I
would never use the interface option), troubleshooting the command using the
interface option is much harder than using the addresses due to someone
stating earlier that it can create loops in the network, proxy-arp issues,
timeouts, testing and ensuring fail-over, blah, blahh...

with broadcast media use interface. advtge is that if
you specify next hop you are going more static than
dynamic-if that nxt-hp goes away and there are other
routers that can take your pkt why not use them.

e.g.
     ____R2...
r1---\
      \---R3...

if r1 goes to any 1 router as next hop then what if
that router goes down ?

if r1 goes to its outgoing interface it can reach
either r2 or r3. (keep arp-timeout in consideration on
r1-- if you keep it small it will quickly fall to
other router)

now, if you are using hsrp between r2/r3 then you
should point to the hsrp address on r1.
