How does the latest AROS compare to a fresh install of Amiga OS 3.1 or 3.9? Is it as usable out of the 'box' please?
I would say that the out of the box usability of AROS is much better than that of OS3.x
I remember that OS3.1 came with almost no programs and NO third party library like mui.
AROS is different. Even the nightly builds comes with tons of extra software, like some archivers, games and lots of librarys, MUI classes, Software development tools, etc.
If you choose to install a Distribution like ICAROS, then you will already have most of the Software that is available for AROS.
