"Looks" aren't everything (but they do count).
- Zastava NPAPs might have the "look," but they have little in common with their Zastava military brothers - not cosmetics, but factory QC on their “commercial" export line. OPAPs were better than NPAPs, in my opinion, partly because OPAPs were built on milsurp components. The ZPAPs at $850-$899 are way overpriced, IMHO. Anyway, same factory, different production line than the military versions.
- WBP (Poland) comes in a number of versions, including a very classic Polish look. WBP's QC is very good so far (IMHO) and they are very responsive. However, WBP is not Radom (Circle 11). But it appears to be a very solid rifle, so far, available in a very classic Polish AK look. Fit and finish (particularly the classic model through Atlantic Firearms) is very impressive. Different factory than the old military versions (although WBP is subcontracted to provide components to current for upgrades and maintenance of AKs still in the Polish arsenal.
- WASR (Romanian) arguably is the closest to their military brothers, coming for the most part of the same production line (or at least used to ... still do AFAIK). Cosmetics are not great, but that's just like their military brothers. WASRs can be prone to QC issues (the infamous canted sights being the most common). Same factory and generally the same production line as the military versions.
FWIW...
