Hi - My sons had both and had several friends that had them. You really do need all of the protective gear and lay down the law as far as rules and safety. We lived in a totally different environment then - we had woods all around us and it was at the height of the popularity.
They had a lot of fun going to the courses - it can be expensive to rent gear (not sure if they provide protective or just basic) but could be a good test.
Airsoft are not nearly as painful - but still need to be careful! Education is the key! Good luck
