Hi Zeroextreme,
Logic does have a Pitch and time stretching tool. It is called the Time and Pitch machine and can be found in the factory menu of the audio editing window. To enter this view, double click on the piece of audio you want to process.
You will need to select Pitch 'n Time LE as the algorithm to be used with this tool as it will not draw its own plugin window in Logic. All of the same functions are available though and there is no difference. You can find this information in our FAQ section here:

If you would like to demo this, you can download the Logic limited demo version here:

Please let me know if you have any further questions.
Sam.
