Extra bit of screen, better thermals so slightly better CPU performance, marginally faster RAM speeds, better graphics performance, better speakers and internal mic, and a much better keyboard imo.

Most of the upgrades are very slight so for the most part if you're satisfied then no not really. I asked myself this question with a base model 15" version from 2018 and I was much less excited for the 16" in person. Honestly, it's just a much better typing experience, but other than that it was pretty similar to me? If you need to pack some serious performance then yeah, but if you're not looking to get 64gb of RAM and 8tb storage, then yours will do the job just fine.
