The OP is from Romania, and from my own experience too, I think you are mistaken. I would think very carefully before starting a PhD in many European countries.

The OP is from Romania, and from my own experience too, I think you are mistaken. I would think very carefully before starting a PhD in many European countries. I'd also ask searching questions of the faculty, ("how many people do you graduate a year?" and "what % of your graduates go on to an academic job?") This applies to the UK and Germany, for example, not just Eastern Europe. There are certainly spots of excellence, but even among high quality UK universities, very often PhD training is on the "apprenticeship" model where you're just thrown into research without graduate-level courses. You can judge the result by looking at the proportion of US-trained staff in EU departments.
