I went from an X to the Max, also for aging eyesight reasons, as well as wanting to consolidate to one device (I’m finally letting go of my iPad mini 2, RIP)... it’s been a fairly easy transition as far as physical usage, probably helped by the fact that the X was basically a two handed device for me. And as others have noted, it really doesn’t feel much heavier than my X. At first the displayed seemed so big - but it didn’t take long to get used to, and now the X seems rather diminutive in comparison. No signal issues, but I’m quite disappointed in the battery performance so far - after a week of use, it’s been barely as good - and often worse - than my X. And the overall performance seems less smooth than the X after iOS 12... in fact the Max feels like my X did on iOS 11. All that is to say, I’m torn whether to ultimately keep it or go back to my X - but for reasons I didn’t expect. Besides the enormous price tag, I thought the size would be the kicker - certainly wasn’t anticipating battery or performance disappointments.
