Aluminium bodies are way less prone to "oilification" (aka visibly shiny areas where one's palm rests), and I have yet to see any Windows laptop where the touchpad is comparable with MBPs in both size and quality (palm tracking, gestures).
> what with glued-in batteries, un-repairable designs and keyboard reliability issues that have been ongoing for years.
Battery replacements are possible even for someone with only moderate experience in hardware work, but I agree with you that the process is more complex than it used to be. Regarding the keyboard: get a 2019 16-inch MBP, it has a keyboard with real keys and a physical esc key.
Quality actually means no need to repair and use it till becomes obsolete. That's why Apple's stuff have drastically higher re-sell value than the competition.
Only repair shops fancy to repair stuff, the rest of us prefer it not breaking down in first place.
A quality product shouldn't be so fragile to component failures. Bad RAM shouldn't entail an entire motherboard replacement.
