I'm an app dev and I get access to most models except for Pixel.
I usually buy a higher end Xiaomi/Poco phone, and iPad Air.
Poco punches way above its price range. Gaming tier phones and a pretty screen for a decent price. 120 Hz screen, smoother video than my monitor, whole day battery life, charges to full in 10 min. Camera is good at night, and zoomed in. Macro camera can read the tiny text on money, the kind you'd need a magnifying glass to see.
Downsides: lots of bloatware, camera claims to have a bazillion megapixels but doesn't scale in quality, probably sells my data to the CCP
iPad Air is complementary to it. It's great for all "second devices" use, especially banks and auth if you have your main device rooted. Apple Pencil is amazing. I think most Apple stuff is overpriced and more style than function, but the Apple Pencil absolutely delivers on function. Also nice for signing business docs. The general iPad feels a little too big and heavy for casual use.
