Short answer: a tie on sound quality. Both are rated 4.5/5 (#20 and #17 of 222 bookshelf speakers), so choose on features and fit.

What the AsciLab F6Bs does well: A slim, sealed bookshelf speaker that mounts flat on a wall bracket, with accurate sound and wide, even dispersion for a great price. Watch for: AsciLab’s own site shows the F6Bs sold out, though it remains in stock through resellers like Audiophonics and Tested Audio.
The MoFi SourcePoint 8 is the deeper-bass choice. A bookshelf speaker with an 8 inch concentric driver, neutral sound, excellent imaging, and wide dispersion that forgives placement. Its bass reaches about 52Hz before falling 3dB, against 82Hz for the AsciLab F6Bs. Watch for: Like other coincident designs, produces diffraction dips around 4kHz and 7kHz when pointed directly on-axis; needs about 10-15° of toe-out to smooth those out.
Buy the AsciLab F6Bs or the MoFi SourcePoint 8 on features: they are rated the same for sound quality at close to the same price.
