Since my mother is Swiss , I'm educating in both german and french , And half of my mother's family lives in Switzerland , I can tell you french is alot more useful:
1. French is easier to learn.
2. In switzerland they don't speak German , They Speak Switzer-deutsch,
which is really difficult to understand if you just learned german

.
3.Germans are well-educated . Most Germans can speak basic english
but most french suck badly in english , so talking french will help in your whole education (Hotel managment).
4. French is a sexy language , German sounds so nazi

.
5. and you could also learn Italian , since that's the third language in Switzerland
