I upgraded from the Galaxy Watch 8 Classic to the Galaxy Watch Ultra 2 and I'm glad I did. The watch is fast, responsive, and I haven't noticed any significant slowdown during normal use. The display is excellent, with nice colours, good readability, and a noticeably high brightness, especially outdoors. I can see it clearly even in direct sunlight, which is a big advantage when playing sports or just using it outside the house. I also really like the overall build quality. The watch feels durable, well-made, and at the same time is comfortable to wear. I also appreciate the larger battery, thanks to which I don't have to worry about charging it every day, and with normal use, it lasts significantly longer than the Classic 8. In terms of functionality, I'm not missing anything major. Overall, I find the Ultra 2 more practical and versatile, especially when I'm outdoors, doing sports, or don't want to be constantly dependent on my phone. What does annoy me, however, is the occasional issue with the Always On Display, which sometimes turns itself off, and the LTE connection isn't always completely reliable either, especially when I don't have my phone with me. Hopefully, Samsung will sort this out with an update over time. Otherwise, I'm happy with the watch and don't regret switching from the Classic 8. On the contrary, I feel like I've got a more durable, better-equipped, and overall more practical watch that suits me better than the previous model.
