Erm. No. First of all, I'm no stranger to flagship phones, having had the Sony Xperia XZ2, XZ3, Huawei P30 Pro and a couple of others as review sample. For the past month or so I had a Xiaomi Mi Note 10 Pro, which I did purchase myself, and in terms of pricing is close to the iPhone SE.
For that price I get a phone that instead of having massive bezels coming right out of 2015 and wasting a ton of space that could be, you know, used for a screen, I get a phone that is essentially one big screen. And it is good. OLED, 6,4-ish inches. Could it be a bit sharper? Yeah. But almost none are, and certainly not the iPhone. Wish also just has an LCD, as good as that might be. Mind you, the Xiaomi even has something that's like True Tone - IMHO Xiaomi does some of the best Android screens, without jaring colors, nicely balanced and natural. Hold them up next to an iPhone, and they'll be about as good.
Then there's the battery. 5260 mAh or something like that... this thing just LASTS. And there's 30W charging, so it won't take forever. Oh yeah, and they don't make you buy an extra charger, it's right in the box. The only thing I'd complain about is that it is some proprietary thing instead of using PD.
256 GB of built in storage (the non pro has 128) and 8 GB (non pro 6 GB) of RAM are also quite a bit ahead of the iPhone SE.
And the camera? The Xiaomi beats the Huawei P30 Pro. It wipes the floor with the iPhone. You can install Gcam, so the processing side is taken care of. And the main camera is huge. As in, your photos will have natural bokeh levels of huge. Turns out that does help in taking good low light photos, or photos in general. Having a decent 2x zoom camera helps too. And another 3,7x camera (though you have to pinch to zoom... the app only lets you jump right to 5x... which is pretty dumb). And an ultra wide. All of these cameras take beautiful photos. Are the results from that one iPhone SE camera a tad better compared to the stock Xiaomi app? Perhaps. But then just switch to Gcam, and besides top notch processing you get a sensor and lens that are on a whole nother level.
Now, MIUI has ads, which are annoying (and could mislead less experienced phone users). But it works pretty well otherwise. And the downside everyone keeps moaning about: the Snapdragon 730G. But in general use I must say... what's the problem? The storage is fast, there's plenty of RAM. The phone is fast. There's little lag. Could it be better? Yes. Is it bad? Absolutely not. It's a good experience, I've had worse with higher end processors. Lets not forget, the 730G is still a modern, fast chip. What good is having a faster processor if the rest is a let down (looking at many other "flagship killers").
