Your premise is faulty. The e-core is one of the more controversial filter discussed here. Some use them and have no issues. Others (and I put myself in this camp) equate the e-core with the OCOD and view it as a low quality product. Champ also has a performance design that is used in the M1 EP and K&N filters. The e-core is a definite step backward, and the design was obviously made to cut costs and put something out to compete price wise (and apparently performance wise as well) with the OCODs.
It is not a preferred filter here. Judging by the filter used and recommended most often, that honor would probably go to Purolator. Others that are highly regarded include Wix and Napa filters.
The performance line from Champ (Mobil and K & N branded) are controversial too but for an entirely different reason: they are, as far filters go, expensive. The quality of the filter is unquestioned, but whether or not its worth the premium Mobil and K&N asks for it is what gets debated.
