I’ve owned:

• iPhone 12
• iPhone 12 Mini
• iPhone 12 Pro Max
• iPhone 13 Mini
• iPhone 13 Pro
• iPhone 13 Pro Max
• iPhone 14 Pro

I still have the 13 Mini, 13 Pro Max, and 14 Pro. The 14 Pro is my daily and I don’t see that changing for a while. The only reason I got a 13 Pro Max was because I went through a period of time where I just needed the bigger screen plus battery life. The 13 Mini is great, but only if you use it for like an hour a day and spend a lot of time on quick things. Otherwise, the screen is too small for extended use IMO.

The difference between the 5.4” and 6.1” is significantly greater than the 6.1” to 6.7” IMO.
