Bigger they are the harder they fall...
Now that's out of way, yeah the MAX is going to take more abuse from the same height. Immutable laws of physics here, no surprise. Drop tests really don't equate to real world experience. Trend is your friend and yes all glass is going to be high(er) risk. Again, stating the obvious if you don't want a cracked phone don't drop it!
I've had the misfortune of shattering a Galaxy S9+ screen from just two feet onto slate floor! And it was in a thin case. It happens all the time. $230 mistake.
A case will definitely protect your phone as these tests show. A while ago someone was dropping phones from 50' onto concrete to show various cases' ability to protect the phones. I'd like to see those done again with all glass phones.
Tempered glass is amazingly strong. However it founders easily if impacted on a tiny area or edge. It will bend and absorb blunt impacts quite well.
