Hey welcome! 😊
I use samsung browser because I really like the fact that it turns to dark mode all the websites regardless of whether the website has a dark mode by itself or not. Then you can use the "summarise" AI feature, which I use occasionally and a lot more other nice functions.
I also use samsung wallet with curve. You can store passes (flights, train, I think cinema too) and club cards like Tesco etc. Of course, you can use Google wallet as well.
I used to prefer and like samsung messages because if you change the theme of the phone it would apply there as well but I use Google messages for RCS compatibility with all devices and because I can have the messages on my browser when I am on my laptop (it's easier). If you have a macbook- I use ~quick share~ to "airdrop" things. In windows I just have the link to windows app and quick share from samsung and it works really well. Google apps are also nice. For example, I use apart from samsung notes (which is great) thr Google keep which you can also access from your PC/mac.
Correction for sharing between mac and windows it's not quick share but "LocalSend"
