You can of course should spread the load out across several servers for
redundancy. DNS clients typically round robin requests between servers.
On Linux boxes, you can also set up client caches which will reduce
requests across the network. Looks like Windows clients and OSX have a
similar caching service.

Bind also caches requests from remote zones as well. I am not familiar
with other DNS servers, but I bet they all have similar functionality.
It may just come down to ease of administration.
