It's pretty hard to compare them all. There aren't any CZ 858s, CZHs, or FSNs in the US or any ORFs, OOWs, or Centurys in Canada. Many have different finishes like different colour paint, parkerizing or even blued like the FSNs available in Canada.
I have CZs and a Czech Small Arms (what Czechpoint sells, formerly D-Technik). I've shot CZHs and handled Century and ORF guns.
Out of all the guns I've handled I'd rate my CSA the best looking, though my CZs, while rougher finished, have never had any obvious QC issues like the canted front sight on my CSA.
Out of all of them, I'd rate the CZs as the best compromise of quality and price.
