Even experienced clipless riders fall sometimes! I started riding with mine last year and now feel confident in them. However, a few weeks ago on a group ride, two of us had just gotten to the top of a steep climb. I slowed to a stop, had one foot out and fell over in the other direction! I think putting the work into the clipless pedals is worth it in the long run, but I guess it also depends on what kind of riding you want to do. Good luck with whatever you decide!
