Honestly, they're the only smartphones I've ever used, going all the way back to the MyTouch 3G. Well, my first "smart" phone was a Sidekick that I got in 2009 or so, but I upgraded to Android and the MyTouch 3G when my cousin gave it to me when she got a new phone.
Since then I've had a Galaxy S, Galaxy S5, Note 5, and I've had a Pixel 4a 5G for a couple of years now.
Oddly enough I've been on the fence about going to iPhone for my next phone. I have a lot of time and money tied up in the Play Store, and I know it doesn't just go away when I get a new phone, but I've gotta take some stock before I make a switch. Apple products have become more and more enticing as I get older. I used to have harder feelings about the phone divide, but I honestly haven't cared the past 5 years, a good phone is a good phone.
