That is a good question, so I'll revive the thread.
It is difficult to choose, as many of the books in BDSM Library have given me exquisite cums. They make up a substantial part of my 'for-keeps' collection.
Power One definitely is a favourite. Yet quite unequal, and when in collaboration I tend to like him least. I know I cannot read 'Rebecca Strip Searched' to the end without collapsing, so I usually open it at a random page. I found that illustrating it with plates by Boris Lopez made it even more powerful, as Rebecca, in his original writing, is a very young girl with a well developed body, and that is what Lopez draws. (Power One told me h'd later changed her age to accommodate more heavily censored sites). Airport Strip Search shares similar settings yet differs much in approach and characters; a proof of PO's skill. What a pity he cannot bring himself to finish a book - except for RSS.
A recent addition which got me flowing like an old faucet was Black Star's 'Rome'. Snuff is not my cup of tea - I'm not yet fully associating Eros and Thanatos, even though I understand it's pretty commonplace - but this book illustrates the advantage of the genre: prior to termination, anything goes, since there's nothing to lose, and a gifted slut can still have some nice cums on the scaffold or the arena - she could not care less about her reputation! The execution itself is mercifully swift (its description is, I mean) and the book's erotic charge comes from the culprit's consciousness stream as her fate and that of her family are explained to her in great detail.
It is unfortunate the online version is completely garbled and to be frank, unreadable. I was able to coax an orderly version from Black Star. He certainly should send it to Jinn!
I am a big fan of Llabmik's nasty humour. I laugh and seep every time I read him. He was gracious enough to give me a cameo appearance in Hamburg Snuff. What a pity this book is still unfinished!
And (to balance the idea that I favour gory fun, which is only partly true) I must salute Y.N. Humiliator (The Continuing Adventures of Lisa James) for his oh so naughty imagination.
(I think the big secret is the mix of naughtiness and nastiness. A book with only one ingredient is plain boring. And properly whipping the two into a froth is each author's trademark.)
So many thanks to Jinn for what is truly a public service. There is much I don't like on the site, but that is the case for everybody, and as long as I can plunder the gems, why should I care?
