SumatraPDF is what you want as a windows user (yes, ignore the website looks like it's from the 90s). No upsells like acrobat/foxit, better compatibility than pdf.js like your browser.

Linux I mostly use evince (included if you use a Gnome based distro), but it's clearly the weakest of Preview/SumatraPDF/evince, as someone who uses all 3 regularly. Still better than Acrobat Reader though.
