Build quality varies widely, which shouldn't be a surprise to anyone. The surprise to me is when the companies are building the same handful of floor plans over and over and can't seem to manage that without a ton of fuckups. All 3 of my direct co-workers moved into a housing tract built by a local mass builder and all pretty much had the same issues with quality and poor execution. Like light switches being installed upside down or to the wrong lights or putting in the wrong trim or the wrong version of backsplashes (sometimes you get free upgrades, other times you get rushed corrections that look like shit). Little things that are fixable, usually, but a ton of them. And as mentioned, using the absolute bare minimum in material quality, which is expected, but then not being able to execute the same floorplans over and over? That scares me.
