The answer is matter of taste, use both in one project and find yourself what do you prefer. (I do Test::Unit, RSpec has to much sugar for me).
Update 2014: As Ruby 2.x has MiniTest built-in I would suggest to check MiniTest::Spec eventually which is simple BDD extension. You can mix "describe" and "it" blocks to nicely structure test contexts with. It also provides "must_be.." matchers if you want to more than assert.
