Open vs closed floor loops?

I don't believe I have seen much said about open vs closed systems from those who are hydronic floor heating. Though I have read the descriptions of there differences what are working floors using? Which is more favorable towards low heat/high mass designs with just one or two loops? Is the type of pex(O2/non-O2) a factor(I know it affects material,metal, choices)?

There are very convincing arguments by professional for each type from what I've gathered.
