I haven't heard those demos yet (and they really should see an actual release, considering how well the Focus and Atheist re-releases have done), but Focus does not "suck". It's probably a 6.5-7/10 release. There are a few really good songs there, but some production issues and some filler.
Masdival/Reinert did way better on Human, which is a 8.5-9/10 in my books.
