Black Library does have some geniunely good sci-fi hidden under all the crap. The trick is to completely avoid anything involving the Space Marines or anything that might affect the setting's status quo. Eisenhorn/Ravenor Trilogies is pretty good. Last Chancers is one of my favourites though, It was written when 40k authors were still allowed some freedom with the setting, its about a penal legion being sent on a bunch of increasingly more clandestine suicide missions. Peter Fehavari's books are an interesting attempt to carve out his little niché. Basically every book he writes, from the full novels to the short stories they write just to promote new models are all interconnected in a very cosmic horror web of connections. Warhammer Crime has some pretty good sci fi in it too, its essentially a series of short story omnibuses and full novels all written by different authors themed around sci-fi detective stories.
To me the Horus Heresy's popularity makes zero sense. I get how someone can sit through and enjoy a marvel movie alright. But how in the hell can someone sit down for hours to read the book equivalent? Its so much more excrutiating to do.
