Sioyek really is amazing, especially for academic-style reading with a lot of jumping back and forth, and very customizable. I also heartily recommend it, but do be aware that there are some rough edges remaining.
If you ever get stuck, there are a lot of additional tricks and workarounds for some of the quirks hidden in the project’s github issues. And if there’s a feature you feel sorely missing check out the main branch version instead of the latest official point release which is a couple years behind now (e.g. still missing integrated dual-page view which the development version has for close to 2 years now)
