Same here, in most cases I get away with the "Quick Erase", so I use this as my default. But I've had some "hard cases" over the years where I had issues either during the burning or ended up with not properly readable CD-RW. In many of these cases doing a "Full Erase" helped to overcome the problem (of course followed by re-burning the image). As this might occur only once or twice a year I don't pay too much attention to it.
