It's not that mac have become much better but that the rest of the lapto pindustry has just gone to shit: 1. Windows pulling more and more shenanigans 2. Normal laptop hardware becoming as pricey as Mac. I could get much better performance as a Linux user from a 1000 Euro laptop that Mac had no alternative for under 2000 Euros. But today, worse performance Linux/Windows laptops are more expensive than Mac. 3. Linux has become much better but the hardware support for laptop is still being bottlenecked by all money going to Windows support. Also, linux has a application ecosystem problem.
I love linux and use it as much as possible. I had a Macbook in 2015-2023 but I preferred linux laptops then. But this year, I had to switch to a new laptop and got a Mac and it is definitely much better than anything on the market just hardware wise.
Software wise I still prefer KDE+Linux.
