iPhone 13 mini (w/ Razer Arctech Pro case) here. My first iPhone (5C) is awesome for single-hand use. SE1 is about the same. To the point my next iPhone (XR) is too big for my fat oily fingers to comfortably use. Sadly, time has moved on, and the display on SEs are garbage by 2023 standard.
Yes, I got questioned by the sales for "You want mini? That's a bit rare...". And my mother doesn't approve my grown-ass adult decision to go small with my phones because "it is bad for your eyes". I know this is by far the most comfortable phone I can buy in 2022~2023 for me other than iPhoneSE2. And I got too annoyed that I snapped and threw the phone with intent of harm, proving its sturdiness. Of course I missed, and things got calmed down shortly after. I was too much of a weirdo back then...
The wacky gamery case is that my phone was constantly overheating under heavy use in a summer vacation in Japan (it doesn't help that air temperature is >35C very often, but somehow it is much worse than in my local areas). I was shopping for another case anyway, and I saw that case in a Don Quijote store with some very Razer marketing. I don't know if it would have helped, as I bought the case after leaving Japan.
When the sad last days of my phone inevitably come, the next phone is more likely to be iPhone-whatever-number with no suffix, although I will have another cold hard look on the Android side of phone market. I'm not that happy with the lack of multitasking power on my iPhone for gamery reasons anyway.
