Maybe it’s just been good luck, or maybe I pay enough attention to what apt is going to do and know how to deal with it but I’ve been daily driving sid for years and am convinced it’s more stable than arch based on friends I have that run arch…maybe it’s just I’m more experienced but it really doesn’t break that much. Obviously ymmv.
The pedant in me dictates I must say you probably mean UEFI and not BIOS
