Both will be disappointing out of the box, but that goes for pretty much any BASR at this price point, and a lot higher come to that.
Both can be made to shoot a fair bit better with a couple of inexpensive parts and a fair amount of work, but you'll still be at the mercy of other players with a half decent AEG.
Similarly, both can be fully upgraded to the point where there's almost nothing left of the original internals, and your wallet is strangely empty....
