RSpec is designed for Behavior Driven Development, whereas many
testing tools are designed for Test Driven Development or even post-
development testing.  So basically, your question could be rephrased
as "What are the benefits of Behavior Driven Development?"  Here are a
few places to look for more introductory material:

Many people use RSpec with Cucumber.  In fact, the RSpec book (linked
below) talks about how to use both of them for effective behavior
driven development.  It's important to remember that tools cannot be
measured on an abstract, absolute scale.  (i.e. There is no *best*
tool because some tools were designed to do different things.)  RSpec
is often compared to Ruby's built-in unit testing framework
(Test::Unit), and many people like the shoulda macros that work with
either RSpec or Test::Unit.

Test::Unit: http://en.wikibooks.org/wiki/Ruby_Programming/Unit_testing

There are several demos available online.  Here's a demo that shows
RSpec, Test::Unit, and Cucumber using Ruby on Rails:

There's also a lengthy introduction to RSpec available on PeepCode:

I hope that helps!
