And even the worst LEDs I've had worked for five times longer than any incandescent.
This is certainly not true, at least of LED's in general. Maybe you're buying a pretty good brand. The LED in the picture is at most a year old and as you can see is only operating at about 30%, which is my book means it failed. Probably failed months ago, which means I got less than a year from that bulb, which is only on maybe four hours a day.
Good LEDs are amazing and last a long time. Cheap LED products (basically most stuff at the supermarket) can be really, really horrible - poor colour rendering, ugly tint, flickering - and are more expensive in the long run because they don't last long (insufficient heat sinking, poor drivers, etc.)
