What do you think of Clear Linux reference stacks w.r.t. FreeBSD's similar offerings?

So, for a while I thought ClonOS https://clonos.convectix.com/ was the best thing since sliced bread.

But then I noticed Clear Linux and its reference stacks, e.g.:

Data Services Reference Stack — System Stacks for Linux* OS documentation

Looks a bit similar?

How do they compare?
