while: 0.141 ~ goto: 0.187
EDIT:
In addition to being faster, IMO while statements show more understanding abotu what your code is going. It shows you took the time to comlete your thought process about what you want the script to do. Goto's, to me, look like you said" Well, i got it looping.. but i forget to do (this). I can just stick a label in there, and it'l work. Sure, doing it the first time, or even second time may not be bad. But when you start repeating that, then you get the all-too-well-known "Spaghetti code"
