They both work to a point. Not 100% spot on, but always on paper at 100 yds. The BSA "optical"(?) type is not good for anything with a high front sight, such as an AR, AK, or SKS, that's where the laser comes in.
Between these two, they would probably give you the most coverage, bore size wise, and once you know how far off they are in what direction, you can compensate and get fairly close. I'm pretty happy with them for the price. Never used a pricey one, so I don't know how much better they would be. More than one shop I've seen uses cheap ones, no better than these.
