I have both BPS and SP10 and have shot the Black eagle. The BPS will kick more to me. SP10 is very heavy and does not kick as much as one may think. In fact, it is mild to the blackeagle and I expect it is the weight. I like a heavy gun so that is not a problem for me. SP10 is gas operated so anywhere from 40 to 55% of the recoil is reduced. Black Eagle is more versitale for using varies shells and loads unless you reload. I reload steel with very good results for all guns. Each gun has their favor loads.
