I also like the German "LiveSystemPro", which just had an update (it will be featured in the German "Computer Bild" magazine next week. For me, LSP has the combined benefits of - a compact builder engine (like Win10XPE had, PhoenixPE on the other hand has a slightly more complex builder based on NET etc), and - up to date and well maintained application scripts Creating a custom PE with LSP is quite fast, specially repeated run throughs after the first build (the first build always has to do a lot of file permission settings, etc)
