I've had both of these controllers. The Wort Hog is good, reliable, but it is no comparison to the BrewCommander. Once you have an electric system with a delayed start timer to come on and start warming your strike water, you'll never go back. But the other beauty is the easily programmed mash steps. I'll frequently do a multi step mash. The fact they take a long time is almost meaningless.
I set the controller to come on and start circulating and heating strike water through my RIMS while I'm sleeping. I set my alarm to get up, go stir in my crushed grains, then press Start on the multi temperature mash profile I programmed in. Go back to bed for two hours, get up, and it's time to transfer to the boil kettle.
If I start early like that, the BC makes it so easy, and I'm done by lunch. If I start later, for that 1.5-2 hr mash time while the controller's doing all the work in the basement, I can be mowing the lawn, doing dishes, having breakfast with the family, etc. It's a beautiful thing.
