I guess it depends on what the common failure mode is. During the 2020 derecho our neighborhood with buried lines was without power for roughly four hours and it's the only time our power has gone out for any significant time in the 10 years I've been here. It wasn't even our buried lines that had the problem, but the lines serving them. Places in the city with poled power delivery were down for up to two weeks. There have been multiple times where houses surrounding us are out of power but ours just keeps chugging along.

Mine's buried; was dug up and replaced overnight a few years ago. If it's slow I think that's just under-resourcing and scheduling rather than it actually taking that long to deal with the specific circumstance.
