Do links from dmoz listed sites have better effect then links from sites that do not listed in dmoz/gogle catalog?
Nope, it won't have any extra effect. Unless you're counting the fact that a link from DMOZ may increase the PageRank of the other page (For example, if in a PR5 DMOZ category), so that would be better. But if there are 2 pages - both PR3 - And one of them is listed in DMOZ and the other one isn't, then the links will be exactly the same.
