Yes agree - the 16 Pro Max has become way too large IMO.If I had skipped the 15 Pro I would likely feel the same. I just find it stupid that Apple keeps changing sizes all the time just for newness sake. They just had a major redesign (their words) with the 15 Pro and made it smaller, lighter and more comfortable than the 14 Pro and 1 year later they are already going up in size again making it less comfortable to hold. Of course 100 % subjective.
I guess a very large handed person can use the 16PM one handed....
I have a work 14 Pro Max and it's too large - it's more a 2 handed phablet..
OTOH my personal 16 Pro is just the perfect fit for my small hand.
