I'm a Taurus so I kinda had to say that but I know that Aries natives are not the best companions. However Taureans are not so bad:
Much like the bull that personifies Taurus, Taurean natives are often headstrong, powerful, and extremely sensual individuals. Taurus is a sign that loves peace, security, and beauty when it comes to all things and they are not afraid of working hard enough to make sure that their lives are thoroughly steeped in these qualities. They are especially fond of some of the finer, more sensual things in life, including but not limited to good food, good wine, beautiful music, and fine art. A Taurus native at his best is peaceful and non-assuming, most concerned with maintaining the sense of harmony he craves.
