I have both. Whether it be dev work or music production, my old 16" from 2018 immediately gets hot and loud. On the flip side, I haven't heard the fans turn on on the new 16", and it barely gets warm. And its battery life lasts sooo much longer for similar workloads (despite me just having gotten a fresh battery replacement for the old laptop).
