Default PDF Reader on iPad vs Note

So I returned my iPad air and everything is awesome. But one thing I can't get over is why PDF viewing on the Note 10.1 is so inferior to the iPad .

The Note has a better processor and more Ram, shouldn't the PDF viewing be super smooth? Is it an Android issue where PDF viewing is so slow?

On my iPad I could use GoodReader to open 4 different PDFs and it wouldn't really stutter or lag, but it seems like all the PDF apps for the Note (RepliGo, office suite, Polaris, and more) all seem to have trouble rendering even one PDF. The rendering issue is especially noticeable when skipping around.

Is anyone else as frustrated as me with the PDF situation?
