Honestly, the Samsung OneUI on phones has little, if nothing, to do with Tizen. Have you tried a newer Samsung Galaxy phone?
As someone who now has a Pixel, newer Samsung devices come across as far more full-featured (I think this might be objectively true?) with a more consistent and pleasant UI (IMO) than stock Android. I don't use it because of bootloader/ROM support, but if that didn't exist I'd probably prefer the device that takes stock Android and adds some polish and thoughtful features along with better quality hardware.
There's a reason why Google has often integrated Samsung features into stock Android with a delay of a year or two. Obviously, the reverse is true and Samsung benefits from Google development, but I think that's already a given when Samsung advertises an update to a new Android version. OneUI also seems to avoid the general slowdowns of older Samsung UI experiences such as TouchWiz.
Yep - I'm using an S10 right now and have been for the last 2 years.
Some problems I have with it :
Bixby is garbage and I don't know why they haven't killed it yet - there is 0 chance they will ever develop anything usable let alone competitive.
It comes preloaded with bloatware I cannot uninstall, custom app store it uses to update it's own system apps, it's own apps are spamming me with notifications constantly.
Supposedly it has good integration with it's ecosystem devices, but unlike Apple - nothing actually works well, SmartThings craps out, Health keeps spamming me when I stopped using the watch, the watch doesn't have Google assistant or Maps out of the box.
Overall the hardware is quite good, base OS is decent (I replace the launcher with Nova), but the apps and software ecosystem is garbage. Apple is miles ahead it's not even funny. I really don't want to get an iPhone because the iOS is so locked down and I want to go back to a Windows machine after the disappointments with MBP thermals for years and outdated design at this point. But Apple ecosystem just works 95% of the time.
I mention Tizen as an example of Samsung trying to pull off their own thing in software and sucking at it (like Bixby). All Samsung devices would be better if they used a competing OS stack. One UI is the shining example of something that works but frankly I don't see the value add over stock.
Thanks for the reply. That's definitely very fair criticism that I generally agree with.
I suppose I personally don't mind the inconsistent and lackluster device ecosystem support because I currently prefer an outdoor watch over a "true" smartwatch. The OneUI additions were therefore what stuck out to me the most, especially from the perspective of a Pixel user. While I would appreciate the privacy and consistency aspects of iOS, I really don't like the often confusingly obscured UI elements, and the limited feature-set is the deal-killer for me as I at least occasionally depend on having decent file management, FTP/SSH, etc.
