I learned to read the descriptions of the various models from each manufacturer a little closer, instead of just shopping by reputation. I have a pair of more expensive assos that I wear less than the cheaper castelli. When I bought them, I didn't realize the f1.13 from assos had a thinner pad than some of their other models. That pair ended up to be great for shorter rides (less than 40 miles), but I always wear the castelli cronos for anything longer than 40 miles. I'm fairly new to cycling, so I'm still trying different brands, but so far the castelli cronos work best for me.
