Everyone is missing the best feature of the motorguide. If you are on the water and something happens to the electric assist motor or any of the electronics, you are not down. You can still steer the MG and keep fishing because it is cable steer. The one thing you need above all else on the water is reliability. I have an ultrex but if something fails, my day, or tournament is shot. Murphy's law tells me things are going to go wrong or break especially with a boat. You need to be ready for it because it is coming. The MG is the only one that lets you keep on going. This factor alone makes the MG product a real contender. If you have any of the others, you will be headed to a service center for repairs while the MG guy is casting on your favorite spot. Like I said, I have an ultrex but I would 100% consider a MG now.
I think we will see MG switch to a brushless motor. They probably had a couple warehouses full of tour edition lower units they needed to move.
