I've got decades of real world photography, plus bench tests. So that trumps both. But it's all about intelligent decisions. I even use things like
blue filters once in awhile, and even flare itself for creative purposes. I wouldn't mind owning an old totally uncoated lens or two for my 8x10.
But there are times to use them, and times not to. Using tools wisely is just part of the craft. But the whole point is what you make with those
tools, not the gadgets for their own sake.
