I started using Google Messages to get RSC but Samsung's messaging app has it also so I tried it. I didn't like the UI so I'm back to Google. It's been forever since I tried something from the Play Store but that's mostly because everyone started putting ads in the feed. When I'm checking my feed I don't want to see;

I use Verizon Message+ and TextPlus. I like them better than Google Messages but, Google Messages is good too. I like the colors and how the app changes color between texts. There always different colors when I use Verizon messages. The text box is a decent size and the photo you attach is big too.
I've used both happily, but I think I stuck to Samsung Messages on my Samsung phones and Google Messages on my Pixel phones. Easier that way. Plus, I think Google Messages ate a bit of my S19's battery when I tried using it on that device.
