UK nationals get a VOA in UAE which lets you stay 30 days. You've probably never noticed because it's free and is just an automatic stamp in your passport. Germans don't need a VOA and can stay 90 days which makes their passport more powerful..

#10, fcg, your original post #3 stated "Visa free or VOA (when UK passport needs a proper visa)" which is just not true with at least half the countries on your list.
I assumed the natural progression was understood. Visa versus VOA or VOA versus visa-free, the latter in each case allows more freedom over the former hence one passport is deemed more powerful than another. German passports are visa free for all those countries whereas UK passports need a VOA. Whether it's free or not is immaterial, it's beaurocracy German nationals are spared.
Before you ask, no I'm not going to check if any VOA for UK nationals is free or payable.

#12, fcg, if you want to split hairs about about the UAE what about all the countries in #6 that do not require a visa, for example Samoa does not require visas from anybody, your list was fake news as they say.
Gosh you clearly don't like the fact that the German passport is more powerful than yours but shooting the messenger won't change anything. I didn't set the judging criteria although they seem pretty straight forward to me - ease of / lack of formalities in passing international borders.
Life is too short for me but you can actually check the entry requirements for all those countries by consecutively using German and UK nationalities. I'm sure you'll find in all cases, formalities exist only for UK nationals and not Germans.

#14, fcg, I did not say what my passport is, and I could care less whether a German or a UK passport is more powerful, I just said that your list is bogus, which it is and I gave you examples of half your list which is all I could be bothered to check. Maybe you need to look beyond your Skyteam blinkers.
Bad luck for you if you think it's blinkered. It's an official site, you won't get on a plane unless you conform to the requirements for any particular destination. The details are kept up to date by the relevant immigration departments of each country - maybe complain to them.

Well I certainly won't fly skyteam (whoever they are) then if they will not allow me onto a plane to Dubai.
