The best. I just wish the auto-hide TOC feature that was available in versions prior to 1.4.13 is supported in all OSX versions as opposed to just 10.6 (as per ver.1.4.22 via SKHideClosedFullScreenSidePanels) since v.1.4.12 just refuses to work on Sierra and I'm stuck with switching command+shift+T instead of simply hovering to the left side to show the TOC panel. MacOS Sierra slow scrolling bug is already ironed out in the upcoming version. For those who can't wait, choosing single page view mode then single page continuous after opening the pdf file *should* fix the problem (tested and works on v1.4.13 or newer)
Best OSS PDF viewer for OS X bar none. Period.
Best PDF viewer for Mac OS X to use for latex editing. I use it with TextMate and i can do forward-backward search and auto-refresh with synctex.
Skim is awesome. Yet, it doesn't work on OS X El Capitan at this moment. Shows only black screen for PDF previews, while thumbnails work fine.
Much smoother than Acrobat when page up and down.
