No, the two are not even remotely comparable. OS3.2 is an upgrade to the official OS, with a large existing software library stretching back decades and far more users than this thing will ever have.
I just looked at this from the link provided… I cannot see what use this is, apart from someone who is just curious and have a play. I own a 128D system. I was thinking about getting GEOS 128. But as I own a few Amigas with AmigaOS 3.1 to 3.2.2.1 where I will have a better experience with RTG and even the native Amiga graphics. My 128D will still only be used for loading games for now….
