For me everything is unplugged when not in use. Last year a tree root broke the neutral feeding the house, fortunately we were home. Each of the "Protected" power strips started smoking and would have caused a fire if we were not home to shut off the power, all the dumb strips were fine. Fortunately none of the major appliances were damaged and are all still working. What did die along with the protected power strips were all the LED lights that were on, the garage door openers, the Craftsman tool battery chargers, and one radio. There are still burn marks on the floor where the computer power strip was sitting.
After the power line was repaired and a new meter put in I looked at getting the garage openers fixed. After removing the control boards I notice two can capacitors that looked funny. In my parts box I had the correct items and once replaced the one garage door opener worked. Encouraged I opened the Craftsman V20 chargers, sure enough there were some swollen capacitors. When the parts came in from Digikey I got them working again.
Had I not been home I would have returned to a smoking ruin due to the power strips. Overall I got off cheap, about $10 in parts and some replacement LED lights. I now pay extra to have full house surge protection from the power company, but still I keep things unplugged since you never know.
