I always backpack in light hikers. Less leg fatigue, very little break in required, better cushioning, etc. However, they simply will not last as long as a good leather boot. Personally, I would return them if you are hiking on groomed trails. Over a few KM's you will definitely feel the weight.
For scrambling or climbing - boots for sure.
