Ryobi has good balance, but the runtime isn't great, power is decent.
Black and Deckers are fast, but don't corner well.
Dewalt has the best acceleration, but lacks strait line stability.
Craftsman's are good as well, just don't have a ton of "rip", good balance and overall speed though.
Oddly, the hitachi is the best all around, great runtime, ample power, and drives easy..........
So How Many Days Now??????????
