Most gtk2-based (or dependent, in case of eclipse) apps I use at daily basis (incl. floating deadbeef settings window with older gtk2 plugin) side-by-side. I haven't included evince (gtk3) as I am using partially broken gtk3-Mist theme (not compact as xfce-b5, but still better than Adwaita). Nothing scaled, cropped or such. Btw, I use Classic Theme Restorer plugin, which also helps with firefox UI compactification.
This firefox theme makes the app's decorations really small. The icons look as if they were designed in 1995, but if there is a choice between slick and compact, I pick compact.
On second thought, Classic Theme Restorer works just as well with the latest firefox dev build.
