I'm assuming all the Wu-line cubes feel similar. I have the WuQue and the WuHua, and aside from the catching in the WuHua (which might not be present on newer batch or stickerless cubes, but that's not confirmed), they have a very similar, swishy, light feeling on the inner layers, and a very similar fluid or rolling feeling on the outer layers.
I've heard that the Wushuang and WuJi feel similar as well, which makes sense, because they're in the same series and use the same basic type of mechanism as the even-order cubes.
I'd say the Valk feels like the WuQue, except blocky. I don't know about 2x2, but I'd bet the corresponding QiYi cube is close.
