Short answer: the Wharfedale Diamond 9.1. It ranks #79 of 100 bookshelf speakers by sound quality; the B&W 805S ranks #81.
On the Wharfedale Diamond 9.1 side: The first design was a pretty good sounding speaker. Set against that: All current new ones sold today are the crap version.
The case for the B&W 805S: Bass and dynamic performance are strong for the cabinet size, playing very loud with well-controlled bass distortion. The tradeoff: CEA2034 spinorama shows directivity breaking down badly starting around 1kHz and staying poor to 3kHz - a wide crossover-region flaw the reviewer called “clearly flawed execution” that leaves vocals sounding recessed.
Buy the Wharfedale Diamond 9.1 if sound quality matters more than the price. Buy the B&W 805S if the price matters more than sound quality.
If sound quality matters at all to you, skip both of these and look higher up the 100 bookshelf speakers instead.

The Two Speakers In Full
Wharfedale Diamond 9.1: Discontinued
Pros: The first design was a pretty good sounding speaker, the speaker was then outsourced to China and lost 1.5kg and was made with cheap parts and sounds much worse. Slightly rolled off in the treble by about 3dB
Cons: All current new ones sold today are the crap version. Discontinued.

B&W 805S: $2500 Discontinued
Pros: Bass and dynamic performance are strong for the cabinet size, playing very loud with well-controlled bass distortion. Horizontal beamwidth stays reasonably smooth through -6dB. Build quality has enough of a “quality feel” that the reviewer said it kept the speaker from the lowest possible rating.
Cons: CEA2034 spinorama shows directivity breaking down badly starting around 1kHz and staying poor to 3kHz - a wide crossover-region flaw the reviewer called “clearly flawed execution” that leaves vocals sounding recessed and masked without EQ correction. A high 4kHz crossover point appears to leave the tweeter’s small sub-enclosure resonating audibly during playback. Discontinued, superseded by the 805 Diamond/805 D4 series. Discontinued.
