Just give me an open OS, an old phone, and a web browser and I'm good. If I need serious computation I'll use a 400-core ephemeral cloud computer with 12 TB of RAM, or a modern GPU, depending on workload.
Yes, there will be many users, especially on here that have their use cases for this extra grunt. But more often than not, for the average person - they will never see or need it.
What, exactly, is your point? Phones should get faster hardware because the UI is slow? Clearly not a hardware problem. Hasn't been one for at least a decade
Apple phones are always fast in the UI. Some is fast hardware, some is software. But if samsung is not able to stripdown android to run decently on a midrange phone maybe they actually need the faster single core performance.
I think the latter is better due headphone jack, speed and the option to record calls.
