Most NuBus video cards do separate sync (the best solution for analogue video) by preference, falling back to combined sync or sync on green, depending on the capabilities of the monitor. Most monitors use separate sync or combined sync, hence the requirement for those special adapters for the IIci built-in video etc.
In my experience using Radius Thunder cards and SuperMac cards they actively use Sync-on-Green. In fact the Thunder cards only support 2 resolutions out of the 20-odd they provide in Separate Sync mode. Off the top of my head they are 1024x768 and 640x480, I think.
