Is 50MB that important? I would just use whatever provides you with the best experience (whichever that may be).
He is either on a low powered device or overly focused on details. In my experience I have never needed to look at RAM usage on my 2017 16GB MBP, but sometimes I do check CPU usage just to see how hard that intense process is hitting the computer and when it finishes.
