I love OSM. Way more than google.
For hiking and cycling it is absolutely supreme to google in every way. Google will often just send you a "car-path" by foot or bike, while OSM will try to steer you to smaller, slower roads/paths (and way more of those are mapped on OSM then on google).
The main issue on OSM for me is the lacking up-to-date business information... If OSM shows shops on maps: don't rely on it. It would be very interesting if the business/reviews/pictures etc part of google maps could somehow make it (open source version) to OSM.
