"AROS One" by AMIGASYSTEM might currently be the most actively maintained AROS distro.
Version 1.9 of "AROS One" - a ABI v0 based AROS distro for m68k and x86 computers - has been released a couple of days ago. Among the updates are new docs in PDF, AmigaGuide, HTML and doc format, themes and iconsets, a new touchpad driver, improved file system support - and as always lots of applications and games.
