Not always. I'm somewhat disappointed with my 2020 16" MBP that I bought after owning a 2015 MBP for 5 years. This one is faster for sure, but also noisier, gets hot often for no good reason (even with the lid closed for the whole day!), takes 7-8 seconds to wake my Eizo monitor, while the previous one would take only a second to do the same.
To be honest and quite unexpectedly the 16" MBP is not the best Mac I ever owned, despite the hype. The display is amazing, the speakers are incredible for a laptop, I'm also glad the T arrow keys are back, but everything else is a disappointment.
Strange, I did exactly the same switch recently and consider the 16" MBP a significant upgrade from my old machine. It even stays completely silent most of the day while the old one would constantly spin the fans.
It is a an upgrade in some ways, no doubt. When Apple said the 16" MBP has the best ever laptop display they were right - it's hard to go back to the previous models after this one.
Something just feels a bit wrong about this machine. Running trivial Swift code in Playground can get it so hot that it becomes uncomfortable to rest it on the lap for example.
Do I need a processor that powerful? I'm not so sure if the price is the unsettling fan noise and being practically constantly warm. And no, there's no 3rd party software that could cause it, it's all Apple apps.
