For me its Classic Workbench, both 3.1 and OS3.9 packs are nice.
I particually like the ADV SP pack becuase it looks just like 3.9 but runs much quicker.
IGame+ the screenshots pack is awesome and I prefer the layout and the Scalos/menu system.
The packs include all the useful tools you need and they're not overdone like I find with Amigasys4 which has too much going on.
