English has about 3 times the vocabulary compared to German. It is easier to use basic sentences compared to German, but the extended vocabulary is where the fun starts - so many beautiful words for poetic things. It is easy to write an uplifting motivation for any topic. However, I find English harder to use in a technical area. Some part of that may be gaps in my knowledge, but.. things have many names and names point at many things (what is 'gear', for example?), and I lack precise verbs. Just my impression..
According to which method of counting?
Wikipedia says [1] that "One most recent 2016 study shows that 20-year-old English native speakers recognize on average 42,000 lemmas, ranging from 27,100 for the lowest 5% of the population to 51,700 lemmas for the highest 5%." and "For native speakers of German average absolute vocabulary sizes range from 5,900 lemmas in first grade to 73,000 for adults."
In general, I'd expect all languages to have roughly similar vocabulary sizes, since they are mostly limited by the ability of native speakers to remember them.

The magnitude of that difference (250-300%!) should serve as a stark illustration of just how hazy these estimates are, even within a language.
Between languages, it gets even more difficult. It's very hard, possibly impossible, to come up with a single standard for what counts as a word that doesn't favor one language over another. For example, I wouldn't be surprised if you could engineer a comparison that says that English has more words, and also one that says that German does, simply by changing how you deal with agglutination. Or, if not that, then certainly agglutination and polysemy together.
Checking for myself my information seems to have been wrong. As we say here, I take everything back and claim the opposite.. That will teach me not to check my facts I hope.

What does this mean?
> English has about 3 times the vocabulary compared to German.
This may be technically true, but as a user of a language, you are limited by your active vocabulary which is much smaller than the absolute vocabulary in either language. In other words, unless you are deliberately googling for synonyms to insert into your text, the larger vocabulary in English does not affect your ability to express yourself.
How about other non-English language authors?
