Highly vote for ClassicWB.
You can try the version that suits you best, although ClassicWB 3.9 on 030 is okey but not the best experience.
Atm I'm using a highly customized ClassicWB 3.9 on 8 colors MWB palette on my ECS A600 (with ACA630@30) with changed iconset on all environment with MagicWB icons.
It also has latest stuff from BB3/BB4 written on a custom Kickstart 3.9 for rebootless boot

Result is really nice for my taste, and blazingly fast even for an 030!!!
