Newer stock, fewer rust failures
Median year built here runs around 2006, which puts most garage doors into the first or second opener and spring cycle rather than the third or fourth. That means less "the whole bracket rusted off the jamb" and more opener logic boards going bad, drive gears stripping on belt-drive units, and torsion springs that were sized right for a heavier insulated door hitting the end of their rated cycle count.
