Only saw Die unerbittlichen Vier so far. It looked pretty decent. It being a Wild Coyote-release I was a bit wary but it actually looked pretty nice. Not pristine dvd quality but I've seen worse. There was a scene or two that was missing from the German 35mm (?) they used as source and an inferior source was used. I noticed a couple of seconds in the trial scene that looked like something taken from a youtube video of bad quality but it was only for a short while.
I watched it with the English dub and that was pretty nice. No silent periods
So at least that one I can wholeheartedly recommend. Haven't gotten around to the others yet.
