The continuous 4 coils of the Blake is more consistent with non-TaughtLine, non -standard 4/6 coil prusiks.
The Blakes, though only running 1 leg of support to saddle, also pulls from both ends of the cord as the 'newer' friction hitches. The leg that doesn't go to saddle is trapped under the first round turn like an anchor or barrel (simply an anchor around self to form eye)hitch. The loaded leg sits across the trapped leg, pulling the trapped leg from the top of the coil stack as the loaded leg pulls from the bottom of the coil stack at the same time. Thus, even though only 1 leg of attatchment as far as strength, similar in function/design i think.
So blake's is better i think than Tautline, as it more closely mimics the 'better' hitches; even though, your eye might say not at first!
Schwab, Distel, Knut, VT, Klem, Heden, Icicle etc. all have a continuous 4 coli/double round turn unbroken, then kept from setting too tight by a preceding bite on line to limit loading to the hitch, to keep it in it's usable loading range of slide/catch/not bind correctly. Blakes is similar (except the others use both legs to support saddle); pulling from both ends, and doesn't let the fiercest part of gripping coil bite. But not by preceding it with a a previous half hitch etc. to bite, reducing load to 4 coil wrap, but jsut not letting the bottom coils seat. The top coils will only have 1/2 pull(but faster) on them from trapped leg being pulled by support leg, the other half of the pull borne on the trapped end.
Or, something like that,
