As a counterpoint, I recently switched from an old iPhone SE to a Pixel 4a and the experience could not have been any better. I find the vanilla Android to be as snappy as iOS for daily tasks if not better.
The problem lies with custom Android ROMs on low spec phones which do hamper the user experience quite a bit
The issue with android phones is knowing which are optimized for speed.
A Samsung Galaxy for example costs almost as much as an equivalent iphone and is significantly less responsive then some motorola phones with stock android
I've switched from an iPhone 7 to an iPhone 11 Pro last year and while the iPhone 7 never struggled as badly the Androids I had before that (where keypresses might take seconds to register at times in the end), it did struggle somewhat to keep up with me at times, whereas the 11 Pro felt (still feels) like a fast desktop computer, in that it never appears like the UI or everyday operations noticeably tax it at all, the UX in that regard is super smooth. I'd expect the SE to fare a bit worse than the 7, since it had an A9 vs. an A10 SoC.
Although I can't find a reference to an aircraft engine, Chrysler did have a variable displacement tech on its third gen Hemi engines that could turn off one bank of the V8.
To the untrained eye, there may not be any difference between the Slav and the Asian one. But if you look closely the Slav squat has the legs spread wider and toes pointing quite a bit outwards as compared to the Asian squat
It's just the matter of what are you doing with your hands - if you want to pick up something from the ground then narrow knees will block your arms from reaching in front of you, but if you are holding something close to your face then narrow knees are better as you can rest your upper arms on them.
