A Good PDF Viewer

No doubt PDF Reader is better than any similar apps I have tried. However, I have noticed it lags considerably when viewing PDFs larger than a couple of pages. Sometimes with 3-5 seconds delay time, which may not seem like much, but when trying to scroll through pages, it gets pretty annoying. This only happens on documents larger than 3 pages, normally. Also, it keeps asking me to rate it…every time I open it…even though I already have.
