Just a bunch of marketing wank - it's all the same product made by the same company targeted at different markets. Same product in a different color at a different price point.
It'd be like a Ford vs Chevy debate where they were both made by the same company!
What I'd like to see is what they all look like after 3 mowing seasons although most people would rather throw it away and buy new every few years. (Oh, battery is dead; buy a new mower!)
Anyhow - end of my soapbox.
