tbh I'd personally go with the G403 (even though it's not one you're considering)
Has a very zowie/deathadder shape, and is an incredibly good mouse. Hasn't bothered me since I bought it (though to be fair it's a pretty new mouse) and I've seen other people who are also just as satisfied as I am with it. comes at around the same price as a DA2013 in the US, 70USD (no clue about switzerland tho) but if it's about the same price there it's definitely worth considering.
