In Europe you get paid more, especially in Switzerland. And in general, English is sufficient for getting a CS PhD in Europe.

Depends on the country and programme, but more and more so. Even France, traditionally not at all known for programmes at any level fully in English, has been making huge advancements in those areas, and there are full programmes in the Paris Saclay university hub entirely in English, exclusively to attract foreigners who don't speak French.

"During the preparatory phase, students take courses to build on their existing knowledge of core computer science areas. Depending on a student’s prior academic background (e.g., MS degree), course requirements may be partially or completely waived at the time of admission."

"Rules in Europe vary. Some participating universities require a MSc, others accept BSc students as well (sometimes under specific conditions). You will find this information in the portal if you click on the list of this year's recruiting advisors."
In some places you technically don't even need any degree, but in practice you wouldn't get accepted without one. (I was looking into this as an option for someone recently!)
Also notice that in Europe you can get a bachelor and masters in 4-5 years (3+1 or 2), which can be the length of a US undergrad degree.
There are also students from the French/Italian part of Switzerland, so there's a natural convergence towards English rather quick, at least that was my experience.
(take this with a grain of salt, it's been a while and my information might be outdated)
