I had a MYLR 2021 with 11.4.4 for a few months on my commute to work. Ive been in beta since like 10.2. About a month ago I traded it in for a MYLR 2023 to do the FSD transfer. I can say with confidence that HW4 11.4.4 is better than HW3 11.4.4. The transition from HW4 to HW3 is larger than any 11.X release to another 11.X release. It is much more confident in turns. I drive the same route every morning and for the first time it did an unprotected left (chuck cool style) flawlessly. It did not have to creep as much. I thin with the higher resolution it can "see" further and be more confident. Anyways just a N=1.
