There are also proponents of Chinese phones who are trying to convince everyone that ZTE/Xiomi/Honor/younameit phones are in no way inferior to iPhone/Pixel while cost 50-80% less. I honestly tried give them a chance - not even close.
I had a Xiaomi Mi 10 Pro and picked it over the contemporary Pixel 4. At the time, I was extremely unimpressed with the offerings from Google or Samsung (I've always been on Android so didn't consider the iPhone) and started looking to Chinese OEMs. They had a wide variety of features and build quality. Some were cheap but some, like the one I chose, felt quite premium, had all the latest features (in some cases better than the Pixel), etc. It eventually got replaced by a Pixel 8 Pro but I would try it again.
I don't think I'm saying every Chinese OEM makes phones on par with iPhone or Pixel, but as with any market with multiple options, some are good, some are not so good. There also seems to be this weird anti-China sentiment that appears whenever these phones come up and I think it'd be a more interesting discussion if we focused on the hardware/software instead of country of origin (not saying that that's the case here, it's just been my experience in the past).
No one reasonable is comparing budget model that cost 80% less is equivalent to a flagship model. The typical comparison is flagship to flagship where a PRC flagship cost 80% and generally has objectively superior hardware if you can live with the software, and tbf many people can't. Or a PRC midentry/flagship cost as much as an Apple/Pixel midentry/budget where the hardware difference is even more noticable. If you're not locked into the ecosystem, iPhone/Pixels are outright inferior, especially in regions where PRC brands have support.
I've been using one of those Chinese devices - a Xiaomi Redmi Note 5 Pro - for the last 8 years. The combination of good-enough hardware and AOSP-derived Android distributions do make some of these devices capable of lasting for a long time. This does not make them "better" than their more expensive counterparts but it does mean they're a much better value proposition. This is not limited to "Chinese" phones, it is also true for some devices by brands like Motorola. It also does not hold true for all devices produced by those 'Chinese" brands since it stands or falls with the device being supported by AOSP-derived distributions. Many of these devices become obsolete long before their time due to lackluster or missing software support by the vendor.
Agreed. I used to own a ZTE Blade. It was an incredibly cheap smartphone and you could CyanogenMod it. Great phone in the performance per $ category. It was honestly the top tier phone in that category in 2010 or whatever. And I suspect these Chinese makes are likewise the top tier in that category. But that's not the category of the iPhone Pro.
Had a few Xiaomis and a few Pixels (9a now). Pixels are better, but more expensive.
Xiaomi bangs/buck was pretty good. Lately they've been upping the price so nowadays they're not clearly the budget option, but a few years ago they were (at least in my part of the world) the best in their price segments.
