I feel that fit and comfort is an incredibly personal thing, but the weight was always fine for me - their design spreads it out pretty well.
The killer feature for me is the deep ear cups. All the Sony headphones touch my Dumbo-sized ears and get crazy warm, the APMs don’t.
Yeah despite being heavier I find the Airpods Max more comfortable to wear than my Sonys. Sony has shockingly shallow ear cups and do get much warmer and the headband is very narrow and barely padded. The Airpods Max ear cups are better and the headband is wide and mesh so spreads out the weight and it breathes too.
The one major downside to the Airpods Max is that they do not have an off button and the case is useless for throwing them in a duffel / backpack, as it doesn't protect the headband mesh at all. I have a 3rd party hardshell case for them but it is very unreliable in actually putting them in "ultralow power mode", so the battery drains.
