I would suggest deciding where you want to settle eventually and what local language to learn before you make the school selection. All of these are local and regional programs so to speak.
If you feel there is a strong risk with work permit issues and other potential problems, then I would pick the cheaper/scholarship program. At the same time, Egrenoble is a more well-known program than Nova (at least to me - Grenoble rings a bell) and this is where you should be doing the research by connecting with current students from your home country and others who are not French nationals to make sure you get an accurate perspective about the effort it will involve in recruiting and placement.
If one of these programs is longer and has an internship, I would recommend that you choose that one.

Congratulations.... do you speak French or Portuguese? Where you planning to work after you graduate or you are going to continue to PhD?
Well I want to be able to work and live in Europe, but I haven't decided where exactly. Maybe UK, France, Germany or Switzerland. I plan to learn French and both schools offer French language lessons. The tuition fee is not really important, however, I have won a scholarship from Nova.
