Sure, I agree, not sure why you are downvoted for stating the facts, both have benefits, Europe in general is less flexible but employees are more protected with more benefits.

All I wanted to say was I don't find 4 months something particularly "nice" as European, though I am sure there are even some Europeans who would find it nice since they work for crappy companies in countries with less protection, so they are in lose lose situation, no US benefits (salary/taxes), no Europe benefits (severance pay/notice period).
