I discovered Okular late in my dissertation-writing. I was pretty thrilled to discover that it could display annotations made with Acrobat. This was my advisor's preferred way of interacting, since I was somehow not able to interest him in learning git or LaTeX. At the time it was far better than evince. I've also found that it does a better job with big complicated pdfs produced by graphviz.
