Tarther is a much firmer ride than something like the T7 or any Boost midsole. I don't know if they changed the material of the tiny lugs on the Tarther, but they used to be plastic and it made them slippery on road, but great traction on other terrain. Unless I'm mistaken it looks like the only difference between the two Tarthers is in the upper construction.
The LyteRacer should perform much more like the Adios Boost. It has a similar heel profile and similar outsole.
I don't know what to make of the Skysensor except that it looks to guarantee a lot of ground contact. I don't quite see how that would make it the best for fast running unless you're a bigger runner with slow turnover.
