I moved from the normal sized iPhone to the Max this year. No regrets so far. The most common thing I do with my phone is consume media so the cumbersomeness has been a good tradeoff.
I had bought a 15 Pro on release day but returned it for the max after a week of continuing to doubt myself after holding a max in the store. I had jumbophones up till the iPhone X, I even had a Dell Streak back in the day.
Most suprising thing to me was that the speaker was insainely better. I stopped carrying a Bluetooth speaker around with me for when I'm working cause the speakers get the job done well enough now. It's not a 1-to-1 replacement but it is just ggod enough that it suffices. Also, the battery life from the smaller phone to the larger was such a big increase that I’ve stopped carrying around an external battery but just keep a usbc cable with my in case my ecig runs out of battery and I need to charge it off my phone.
It’s been an interesting series of trade offs going back to a larger phone but then again, the bezels and thickness have reduced so much that a Max without a case feels the same as a normal size phone with a case. I thought I'd get bit by the screen being too big more than I have but I guess some honest self reflection on what I actually use my phone for compared to what I picture I use it for helped with the decision making. (I totally get that other people's use cases with have completely calculus)
