Tbh it's not just the sd cards. I also dislike the whole ARM ecosystem.
It's funny to say this but UEFI is a million times better than any arm vendor specific boot solution.
Also, lack of arm builds for some packages also gives me some headaches sometimes.
X86 might be more energy inneficient but it just works.
