I leave it off. The chargers will charge the batteries without the battery select switches being in the on position. I prefer not to have anything non-essential energized when I'm not on the boat. The bilge pumps and the chargers bypass the battery select switches (at least on my '03 35 Open).
On an unrelated note, I also close all the seacocks and have a sign that I put on the helm to remind me when I power up the boat.
