redmax stick edgers?

Redmax has two different stick edgers, one is a straight shaft and the other one has a cured shaft. Does one works just as well as the other? Both has the same engine.

 

Less torque in the bent shaft. Supposed to be better for vibrations, but I'd get the straight shaft.

 

I got the curved shaft was a lot less $$ and works great it replaced a kaw. that was stolen. I'm very happy with it.
