Upgrading apple watch, 11 or ultra 3?

I went from the 40mm aluminum SE 2gen to the 49mm titanium Ultra 3, and the positive differences start right in the form factor, not just because the touch area of the Ultra 3 is much bigger but also because it doesn't have that annoying chamfered design with round edges that make it hard to identify exactly where the touch surface actually ends. The action button is also a really useful highly customizable addition that can be used to activate many basic actions on supported applications as well as run your own Shortcuts, which currently I have set to launch the Workout app but dropping waypoints on the map also feels appealing in my personal case. The improved localization accuracy in less than ideal conditions and long battery life while using the GPS are also very welcome additions in my opinion. The internal speaker is good enough to actually enjoy music played through it, making them better than those built into many laptop computers.

The siren doesn't seem that loud, but there's also a chance that I might not have let it run for long enough for it to reach peak volume, and I'm not going to test that now since it's already 10PM here and I have some elderly neighbors, however I can record an audio clip tomorrow if needed. The only thing that I can say about the cellular connection is that it works, based entirely on the fact that I cloned the eSIM on my iPhone to the watch and it registered to the network successfully, so while it can't be used simultaneously with the iPhone because both are operating the same number, I don't find this to be an actual problem because the watch takes over when it's on my wrist and away from the iPhone, whereas the iPhone takes over and shares it with the watch when both devices are together.

The Ultra 3 model that I ordered is the one that ships with the titanium Milanese loop, which I bought on a whim, and was on the verge of returning after learning that other versions of this band actually pull hair and have magnets, however when this one arrived I was pleased to realize that at least this version of the Milanese loop don't actually pull any hair out of my skin, and that its buckle is now mechanical so it won't influence compass readings, The titanium on both the watch and the band makes the combo relatively heavy compared to the standard aluminum case, but material difference really adds to the weight and the difference is not even that small.

Of all of the things I have heard about Apple watches, is it sad that the only feature so far that interests me, is the ability to drop waypoints on the map while exploring the world? Seriously.
Would you consider doing a review on your ultra 3 at any point?

Edited for typos.

I don't consider myself a good reviewer since I tend to focus only on the features that I care about, but I can answer questions if anyone has them.

As for the Siren, I just tested it again, and while it does get uncomfortably loud for anyone wearing the watch, the tone is quite high pitched so it's easily muffled even by just covering the watch with one hand, which I found out completely by accident because one of the patterns played by the Siren is the SOS morse code and I didn't want to make people potentially think that I'm in danger.

I‘ve been using an Ultra since 2022 and I never want to miss the better speaker, better battery life, more precise GPS, the action button, and the not-rounded edges on the touch screen.
Since September 19, I use the Ultra 3 and the speaker is much better compared to Ultra 1st Generation. As said already, much better than most laptop speakers out there.
However, not all people like the much larger and thicker design language.

That is interesting that you find the Ultra 3 speaker better than Ultra 1. Thank you for sharing. Now I want to upgrade! Everything seems to be the same size between the 1 and 3, so I wonder what Apple did to improve your experience.

The eSIM cloning was so uneventful for me that I can't actually remember much of it. I already had an eSIM on my iPhone Se 2gen, and although the Apple Watch Ultra 3 was delivered last Monday, my reluctance to update my iPhone to iOS 26 at the time rendered the watch useless for a while, and after finally filling myself with courage and updating the old iPhone to iOS 26 I did not clone the eSIM as well because I also ordered an iPhone 17 Pro so I waited until it arrived, which it did last Friday. Transferring the eSIM to the new iPhone was not possible because I had already reached the maximum number of device activations with that eSIM so I had to generate a new one through my carrier's app, however I can't really tell if I did the cloning through my carrier's app or just did it as part of the normal cellular setup process from Settings on the watch, I just know that the whole process was really seamless.

My carrier lists both devices under the same eSIM, and I am currently on the fence between also cloning that eSIM to my iPad Mini, which is the cellular model but currently doesn't have cellular service, or getting a dedicated data plan with its own phone number instead. If I do decide to clone the same eSIM to the iPad I will report the experience here, which I assume will be similar to the process that I went through on the watch.
