These aren't comparable; Miele is on a different level. In particular, Miele washing machines are properly repairable. Of course, they're also far more expensive.
EDIT: Missed AEG. These are essentially three tiers of product.
AEG is Electrolux's "premium" branding. In most cases, the same washing machine with different plastic will be available as Electrolux and Zanussi. Very much mid-range; better than Whirlpool/Hotpoint/Indesit, but that's not saying much. Should not be expected to be super-long-lasting.
Bosch (and Siemens, Neff; again, just different branding for the same thing) are definitely a step up. Some though not all machines are very repairable.
And Miele is a huge step up again. All machines should be properly repairable.
I've had my Bosch washing machine now for over ten years and there have been no repairs whatsoever, so far.
For every vocal person with a broken unit, there are multiple people with working ones. These planned obsolescence debates are mostly pointless without actual data (case in point: arguing about WD vs Seagate before BackBlaze started publishing their data)
My 13 year old Miele washer and 9 year old ASKO dryer are still going strong without any signs of their age - and they are being run hard, what with three small kids in the house an'all.
And this is coming from an acquaintance of mine, who has installed and serviced white goods for over 30 years.
Consumer gear of all kinds is crap. You have to go where the pros go, and that isn't even a sure thing.
“They Used To Last 50 Years”

Try finding a washing machine these days, that will last for more than 5 years or so before something breaks and renders the machine useless.
You may be able to find an industrial machine, made for hotels or laundries. But it will be very expensive and likely be huge and it will need 3-phase power. It will also likely not have a spin cycle, so you'll have to either air dry your clothes for ages or buy a separate clothes spinner (most driers need the clothes to have been spin dried first).
Whether I buy a cheap Whirlpool or an expensive Miele/AEG/Bosch or whatever, the quality and longevity is universally shit.
