Assuming that you are not a native of either country or fluent in either language, then the French schools are the ones to focus on: they are stronger for finance, get better outcomes for international students and have better careers services.
Between EDHEC and Skema are the classic choices between higher and lower status schools. While EDHEC has a clear volume and research leadership over Skema, they have similar students, curricula and similar outcomes. EDHEC has better connections and the best career services of these schools and, unlike Vlerick and Skema, students are brave enough to move into employment a bit slower by waiting for better deals. As a result, compensation is higher and value is better.
However, if you want to do corporate finance, I don't understand why you have applied to these specific programmes. Both, and especially Skema, seem oriented towards investment management rather than corporate finance.
Do remember that both EDHEC and Skema have specialised masters in corporate finance management, with majors in financial analysis and management that seem well designed (especially at EDHEC). I would choose that over the MSc you have applied to at either school.
