I tried both with my footwear and actually kept the KTS. They are both good for the intended purpose, but for me the KTS binding worked better with trail runner type shoes/boots than the Kahtoola binding. Also, the trail pro front points stick out kinda far for hiking use in my opinion--the KTS points are oriented downward. Fronts get caught on stuff easily, and if you really need frontpoints then you should probably to step up to a general crampon anyway. Trail pros are a lot cheaper, which is worth something.
I also compared the Kahtoola microspikes and the Hillsound trail. I picked the hillsound trail because...they were on sale.
They do have a little more underfoot structure and a sorta "power-strap" that I prefer over the microspike design.
If I was only going to have one it'd probably be the Hillsound Trail, partially because they're less than half the price of the KTS.
