Customer satisfaction and reliability surveys are limited by response bias, else why don't they all return the same results every time? Many are close, sure - but never the same
German cars are generally the best engineered, in my opinion. My GF has a Golf 2.0 Bluemotion, which is a lovely car to be inside - great toys and a nice interior, great engine and magnificent economy. I now know what people mean about VAG steering though! Perfectly acceptable, but definitely very light - even with the bigger alloys and different suspension setups.
Her old 120d handled better and was bumpier she said, but she was intimidated by people trying to get her to "race" (she's only been driving 18 months and still a bit nervy at times).
My Focus has aged badly in terms of looks (07 Titanium built in Spain!), but handles far more confidently than the 11 plate Golf - no question about it. Having only owned Fords myself (but had plenty of experience with others), I am perhaps very lucky to report back that all of mine have been reliable - only consumable parts needed.
Then again, perhaps I am the exception, rather than the rule

(knock wood) in the 80k miles I have put on my diesel, I've only had to buy bulbs, tyres and brakes in addition to servicing. It's *just* about ready to have the original wiper blades at the front replaced
The Hondas I've driven are mechanically very sound indeed. Bit more rattly than I expected, but good fun. The Civic had reasonably weighted steering, but wasn't as sporting as the low ride height would have you believe. Focus handling definitely trumps the EX Civic (previous shape to the current) as well.
Pointless poll, though. Mainly because cars are built all over the world by different nations to those the badge represents.
I haven't voted, as the "best" is subjective and
not salient fact - something I think the OP is clinging on to ...
