Automation all the way. It allows you to consolidate operations by being able to focus on other things.
For me, I can brew more if my brewday is less. By automating the strike water heating, mash temp and sparge, I can shorten the brewday and clean while the day is in progress. My brewday is normally 4 1/2 hours for a 10 gallon AG batch, including cleanup. That allows me to do it in the morning and not impinge on "family time"...so I can brew more often.
Which is the whole point.
