Having seen OSB fall apart when it gets wet vs plywood which can delaminate but is still solid wood, I would disagree. OSB works if you can ensure it stays dry.
Not better just faster to put up, all those expensive cheap track homes and luxury apartments going up they are not made or built better not by a longshot.
Faster and cheaper to put up is better! Modern insulation is more comfortable and saves you on utility bills; modern electric is safer and supports more usecases; it's easier to attach things to drywall walls than plaster; etc, etc, etc. "The old ways were better" is rosy retrospection.
