I started with WinPE before I ever heard of BartPE. When I found out about BartPE, I wouldn’t give up my version anymore It does most of what I want it to do, and so far I could always get everything (well, it's not that much) to work. APE is really used in an industrial environment. We use it to preinstall systems, to refresh test-systems (with Ghost32), to do basic tests and Anti-Virus runs on systems from customers. I want to make sure my PE is legal, and working perfectly so therefore I stick with the official WinPE.
