> You say this is for efficiency. I use an edelrid mega jul in guide mode on trad but it is no faster to set up or use than normal belaying. I only use it for comfort or for more freedom to move
Except that you can have a drink, take your shoes/rucksack off, sort the rack out and take a picture without the need to keep the hand on the rope. Of course, if it's really easy ground, you just have to keep pulling the rope, but if your second is slower than that, you can definitely enjoy using guide mode.
After couple of pitches (the longest I have done this year was 16 pitch route, but we pitched it in 18 due to wandering off the route a little bit) you really want to relax a little bit.
I use guide mode whenever it is sensible (i.e. if belay is not complicated and marginal). I like Pivot so much that when I dropped it in Dolomites, I replaced it by ATC Guide in couple of days time, but ended up buying Pivot when I got back home. It's so much sexier!
