I really liked Sioyek as a more fully-featured Zathura, but two features kept me from using it as my primary PDF reader:
1. Can't open multiple PDFs at the same time: Trying to open a second PDF with it while it's already open with some PDF crashes both instances.
2. Annotations are stored in a separate document rather than the PDF itself.
Other users have noted both of these before. I didn't find an easy fix to 1, and a partial solution to 2 uses an extension, but IIRC it still requires manually running a command to transfer annotations to the PDF document itself.
