You know it. Using big saws in big wood is not tiring and you can go long time (as they say in Bangkok).
My first saw was an MS 310 Farm boss - 59cc landowner saw, with 20in bar. Okay, not great. Next saw was the 460 workhorse (also 20in bar) and man, was it so much easier to cut wood, and despite the extra weight it was so much less tiring. And so it stood to reason .... etc etc
Anyway, I'm sure the little saws are fine in puny softwood, but when you get into serious stuff, you need DAMANSAW. While I'm a Stihl man, I would grudgingly accept a 395 if inducements were offered. You go swing that big saw and get some lead in your pencil

Where are the pics, BTW?
