I find any comments "that the latest MBPs are an underwhelming upgrade" to be funny.
Apple, or any computer manufacturer, is not going to release a groundbreaking laptop upgrade year-on-year.
One of the reasons Apple moved to its own designed silicon chip, was the frustration that Intel chips were not improving on a regular basis. The MBP M2 Pro/Max are a statistically significant CPU/GPU specification upgrade, in some cases up to 30%, compared to the MBP M1 Pro/Max released only 1 year 3 months ago. That in itself is a good upgrade, not to mention the other incremental improvements to HDMI 2.1, Bluetooth 5.3, WiFi 6E, etc.
The MBP M1s were a huge upgrade on the previous models, and I don't think we can expect huge upgrades on the MBPs every year! At any rate, most people should not be expecting to need to upgrade their laptop every year!
