Xiaomi, of course, but until we know the cost of each SoC we can't really judge. I was trying to find something equally good (or bad, depends how you look at it) with WiFi 6/6E for 200€ and I couldn't find anything. Although there are phones with both 5G and WiFi 6, mainly from Oukitel and similar brands, but they pack tragically slow eMMC storage, or dim 720p displays, or they have no 3.5mm jack and/or microSD slot, or some other fairly significant trade-off. Idk, I mean I agree with you that WiFi 5 sucks, but it's a cheap upper-low-range phone, so it's tolerable when it's very good in many other things. Plus, as you initially said, long software support (something that won't happen with Oukitel, for example).
