Reflections and refractions don't just work. You see no caustics at all unless
you enable them and tweak settings. You see incorrect shadows if you don't use
the proper keywords/settings. Etc. Many things don't work if you don't enable
them.

I have seen so many scenes where you still get radiosity artifacts no matter how
hard you try. I'm not an expert so I might be wrong. And with max settings the
speed difference is not _that_ big after all.

Yeah, since each pass in brute forcer is pretty fast, you get to see something
very quickly. And you can quickly decide if the scene needs more tweaking.
