There are many advantages and disvantages to buying a World of Warcraft powerleveling or a used World of Warcraft account. They both serve similar purposes in which you can start playing at a much higher level rather than starting fresh at level 1. You can even have the character trained the way you want as well. The disadvantage of a WoW power leveling session is that during the session you wouldn't be able to log on and play the character until its been completed. So for a little downtime you get to have your character at the level you want at next to maximum speed.  But unlike power leveling, you won't have some privileges if you buy a used account such as naming the character with what you want and training the character the way you prefer. Along with that you may have to live with the reputation that the previous owner lived up to. It may be good but not always. It's a little risk that comes with it. Both methods are great, as for pricing, I would think a used account would cost less since. Power levelers usually have their own rate as to a player quitting the game and selling their account. If you prefer to have a more fresh start, go with power leveling.

Buying a used World of Warcraft account is very similar to power leveling. The advantage is that your character will likely be geard with some nice equipment and you won't need to spend the time waiting for the character to be leveled. It's a faster option of power leveling. If you prefer the speed then a used account would be optional but of course you would need to spend the time finding the account as well. If you buy a WoW power leveling session you are basically just hiring players to level up your character in which can save you time. Power leveling sessions are really cheap, normally alot less than the $5/hr minimum wage offered in the US because most of the workers who are leveling are based in China. Not only that but they normally are able to level faster than the average player considering they have workers rotating shifts along with many many practices in the game. One of the best part of leveling a brand new character is that you will have a fresh reputation of the character and you would be able to name the character as you like.
