See bug 1752862 comment 12 and following. If this is something people find in need to change frequently, we should consider tweaking the default.
The page delta mode is more similar to other GTK apps, but for the web where there are a lot of scrollers it might not be a good default. The pixel delta mode is more similar to what GNOME web does, and it seems fast enough in my experience.
Either way filing this at least for tracking this potential behavior change.
