Super Fast and can open up PDF files that the default reader has trouble with.

None of the files I tested with actually reflowed when I went to the Reflow view. At best I got the text with hard breaks in the same place as the original text. At worst, I'd also get question marks between every word. And in no case could I change pages while in Reflow view. C'mon. Reflow means actually flowing the lines back together as appropriate for the new display size. Yes, it's hard.

I’m so excited to find MuPDF in Windows Store… Please make it keep zooming level when I switch pages, and add support for (multi-color) highlighting. Make it the best PDF viewer on Windows RT!

Pretty much the same as the Reader if you don't have it.
