I have been using Samsung devices for 10+ years now. Currently rocking a 23 ultra. Had iPhone 11 before my S21, which was the previous phone of mine.
You can rest assured that this phone just blows everything else out of the water. 120 Hz screen with incredible quality makes everything look even more smooth. Processing power+ smooth/fast UI is also going to help you so much. You won’t be feeling any kind of stutter for the lifespan of your usage. My friend’s 14 PM seems less smooth and so “regular” to me , after my experience with ultra.
I hope you have a great experience with it!
I agree with the comment about the case.
I switched to 23u from regular 21. I loved smaller phones for ergonomics and I still do. But lesser battery life cause of the smaller battery made me switch to ultra and try it. When you use a case with your phone, you don’t feel any sharpness at all. One handed mode also helps when you need 1 hand and a smaller screen to operate. Overall I am glad that I went for ultra for the boxy design, extra screen when you need it, extra battery and 10x optical zoom. Extra storage and RAM was also a bonus.
