You know what you are looking at when you get inside one
Not really, but I do know what makes sense (and supplying a double oven with a fused 13A plug on it doesn't either! But I digress...).
So which brands would you still rate?
I think it's really hard. I wish I'd had a chance to shop around more, but this last Neff purchase really was Hobson's choice - "we have this one in the showroom; it fits the space; we can deliver it this week." Alternative: no oven, indefinitely (1st Covid lockdown, when everyone was panicing).
There are a few 'new-teardown' channels on YT, but rarely do they do things I'm interested in when I'm looking, and you need to dig deep also. For example that heating element - who'd have thought it could happen? Actually, there was quite a bit of discussion about the problem on various forums (which I found after it happened), but 'melting heating element' is not something I'd normally Google!
So I like Liebherr for fridges and freezers - the build quality IS good. But they don't do other white goods. They will, however sell you a giant crane should you have need. Brilliant company, IMHO.
Miele have come in for some stick recently as they don't seem to be as good as they once were, although I have repaired both our Miele washing machine and dishwasher fairly easily (once Miele spares (who seem to be pants) sent me the right door seal for the WM).
Beware of many modern washers: the big brands use plastic outer drums, that are plastic welded to be one piece (last part of the drum assembly process). This means the spider bearing, the really chunky one for for the spinning inner drum, is no longer serviceable, and the machine is scrap if it fails (and they do, often. I think I can keep ours going for a while yet, but will replace when we finally downsize. I'll look for brands that have a commercial/industrial division (e.g. make washers for HMO owners who operate communal laundry rooms, for example).
Cookers: really no idea presently. My sister's on her second or third induction hob after an expensive (but nice) kitchen refit about three or four years ago (they're all electric, with oil CH). That is unacceptable to me, so again I'll look for a manufacturer with a toe in the catering industry, if I can.

We bought a tumble dryer recently, when our Creda machine, a mere 41 years old, finally seized its motor. That was a challenge to source!
Unexpectedly, I ended up with a really cheap one, a Candy CSE-V9-DF80 (I think, anyway it's Italian "Hoover", made in Turkey). I wanted an external vent, and reversing action (so sheets weren't knotted and clothes less creased). It's surprising how many big brands don't offer these simple things.
I did NOT want: colour matching to the scullery wallpaper or the washing machine; any sort of condenser, heat exchanger, sewage recycler, or connection to Google or subscription to Apple Music (or whatever).
Despite being cheap and functionally simple (or it should be), It has the stupidest and most absurd control panel I have ever seen on anything, anywhere, ever. Ever.
The icons on the control panel are, as I type, being decyphered by a team of academics at the British Museum. The main theme has been teased out mostly, something like,
"So you want to just dry clothes? Ha ha ha ha..." (this is repeated in three or four places, which made it easier, I guess).
It connects to an Android phone (which neither of us own, and WHY anyway), but uses something that isn't Bluetooth. There is a Candy app for Apple, but that doesn't work ("Sir needs the posher unit, which costs more as it uses tech from They-Saw-Me-Coming Integrations Inc.").
Despite that, it is still capable of managing the first missile exchange of WW3, a thoughtful touch which it explains in the instruction booklet via internationally standard cartoons (probably - the few words are in Turkish, presumably). Drying clothes is, apparently, trickier.
Incidentally, the "new normal" is a single, low-power heating element. I can't blame Candy (except for being gormless): Nobody has explained to the EU that this is LESS efficient and less 'green', than a high power one, or (crazy-thought!), giving consumers the choice of the temperature at which they want to dry clothes.
So, if you do manage to start it (DaVinci Code training required), stuff usually comes out damp and needs to be done twice, but NOT creased.
If only they'd thought of all this back in 1985, when we bought the old one!
Aside: It is tempting to see if I can source a second heating module and somehow wire them in parallel (bigger relay probably needed).
I have also given serious consideration to ripping the control system out and replacing it with one whole microswitch (on the door) and a timer. But I'd have to figure out reversing too, and presently life's too short, and we hardly use it anyway.
I realise readers might not believe me. This is the intuitive control panel:

Obviously the WW3 bit had to be redacted.
The beast is off in the picture, but when you turn it on the display says "duck and cover" for three seconds (in Turkish).
Honestly, I feel on the whole, white goods makers are pretty combative towards consumers, and certainly don't want you knowing where they recently cut corners.
