I hope you are happy with your choice. It’s a rough choice between the two. I went to a max phone for the first time this year. Well, I’ve gone there a couple times this year.
Originally bought the 13 Pro and have returned it twice to try the 13 Pro Max. Currently on my third try. Love the Max screen, battery, and typing comfort. Like the size of the regular Pro. I have reservations that I’ll grow tired of the size of the PM.
I use my 2016 MacBook maybe once a month so I do 99% of my non-job computing on my phone. Don’t own an iPad.. This is the reason I’m thinking the 13 Pro Max makes sense for me. I just need to convince myself of that now.
Again, wish you all the best with your choice. Keep us posted on your experience.
