I've had maybe three or four high-friction upgrades on Ubuntu over the past 15 years, where it wouldn't boot properly until I fixed the problem. So yeah it's /better/, but it's far from flawless. Note I don't stick to LTS releases. If I only upgraded to the X.1 LTS releases I expect it would have been smoother.
