I use preview all day, every day, often with dozens of files open, including full scans of the full OED (each pdf 100s of MB). It occasionally will hang when I "print to PDF" with a large document, but other than that no issues to report for a couple years now on M1 and M2.

Preview also supports reloading the PDF on changes so you can have a similar workflow to Sumatra:

open - edit - reload - edit - reload - edit - Preview crashes - reopen - edit - reloads - edit - Preview crashes etc.
