The only issue that I could forsee a problem with PureOne filter is the limited flow capability after it filters the oil for a while. Depending on the bypass valve differential setting, it could go into bypass mode faster than the EaO, depending again on the amount of crud and crap in the engine crankcase.
That being said, I have used just about every brand out there at one time or another, and the only ones I stay away from are the super el-cheapo no name ones that you can tell as soon as you look at them that they aren't going to filter much.
As much as I like the construction and figures of the EaO, the PureOne seems like a much better "deal" with filtration though. Right now, I have on Royal Purple filters (don't go there!), as they looked pretty decent in construction, but are a little more pricey than the PureOne.
In the end, it's whatever will make you happy that will win the filter battle that goes onto your engine block.
