I've owned both. Both are well made. The Chinook probably has a better finish and mine was a bit faster than my Killum. It's not twice the bow, by any means, but I'd say the Toelke is the better of the two, though not by a huge margin.
Neither grip fit me well enough for me to be as consistent as I wanted to be, which is why I didn't keep either one. I've found a higher grip suits me better. That's not a knock on either bow. It's just me. I wouldn't hesitate to recommend either bow. If money isn't an issue, go with the Toelke. If your budget doesn't allow it you won't be disappointed in the quality of the Kota.
That probably doesn't help your decision though...sorry. If you can, shoot both before buying. Or do what I did and buy used. I'm pretty sure I got my money back on both, maybe less the shipping.
