They are fine aeroplanes.
I don't think they are at all. Any modern aeroplane that has a serviceable autothrottle that will not wake up when the aeroplane is 30kts below Vmin is not "fine".
Any modern aeroplane that has TOGA buttons that won't work at any point (within reason) is not "fine".
They're just like cars and software. Each has good points and bad points but the humans that design them are too pig-headed to incorporate the best bits into one design because "we know better".
