I have the exclaim uhp gmax I think is what they are called. They do well in the rain, haven't put them through much snow. I can't give a detailed review since I haven't pushed them. I bought them because of the lightweight good reviews and the cheap price, the treads look cool too, there was a pretty big weight difference between the different brands too
I have the General Altimax HP's. They were a replacement for the crappy Bridgestone OEM tires. Way more grip in the rain with no signs of hydroplaning. As I have a set of winter tires, I can't comment on the snow grip.
