In terms of rep­e­ti­tion and annoy­ance, yes, the two are very much alike. But they’re fun­da­men­tally dif­fer­ent in this way: Pre­fixes give us con­trol of our hack­ing des­tiny. In the past, we had to invent a bunch of parser exploits just to get incon­sis­tent imple­men­ta­tions to act the same once we found out they were incon­sis­tent. It was a wholly reac­tive approach. Pre­fixes are a proac­tive approach.

via A List Apart – Pre­fix or Posthack. This is an inter­est­ing opin­ion but I see the logic, elim­i­nates the pos­si­bil­ity of bro­ken CSS styles as browsers change and cre­ate new stan­dards and abilities.
