Familiarity: I've used it several times
I recently made the move from LOOK to Shimano pedals. I have nothing against LOOK and continue to support them and like many of their products (indeed, I still love the feel and tactile click-in of my 20-year-old LOOK pedals). However, I recently got a new build and decided to go with Shimano for a number of reasons, but namely because I'm on the tall side at 6'3" and 195 lbs / 90 kg, with a size 13 foot, so I wanted something with a wider platform to give me stability when I'm sprinting or climbing in standing position.
I've been quite pleased with the performance of these pedals and I also love the fact that they offer a solid click in feel and sound. After using them for 6 or 7 rides, I would say that I can click in without looking down about 75% of the time so far, and I expect that to go up to 90%+ once I have more rides in and have the muscle memory of where my new cleats are.
