Your a roadie who lives in Switzerland. I reckon the most versatile bike for you would be a cross country fully or a lightweight trail bike - you're just not going to enjoy riding something big and heavy that much. If you don't want to spend too much, then a mid-range hardtail would be a wise choice, but I can't see a hardtail keeping you happy long-term with the terrain Switzerland has to offer. (Ooooooo, I'm jealous! I'd love to go riding in Switzerland!)

P.S. I ticked all the hardtail boxes, and I'd have ticked all the fully boxes too if I owned one!
