I've used platforms, clips and clipless. At this point, I'll most likely never use anything but clipless again. Platforms are ok but there are occasions where I lose contact with the pedal. Powering up a hill in foul weather, or spinning fast at times. Also, I make a conscious effort to pedal in a full circle, or as close as I can and not have any dead spots. You can't do that on platforms. It's been years since I've used anything but clipless on anything other than my fat bike and I have campus style pedals on those. Platforms on one side and clipless on the other.
