You won't regret it, pro max for the win, Face ID, better battery life, better battery life in standby mode, a14 chip best in the business, better written and looking apps, better eco system, better customer support, better security, 5-6 years iOS software updates, no lag or stutter, better software.
Want me to keep going?
If it ain't a iPhone it ain't a iPhone.
Had 2 family members switch from Samsung, one had a s10 and the other a note 9, they ended up getting a 11 and 11 pro, said they wished they switched sooner, they'll never go back to Samsung, they love Face ID and the awesome battery life, and a million other things.
