Ok, so one thing I'm terrible at is describing the taste of food, so I'll try my best: it has more flavour than beef, but it's delicate flavour and doesn't taste gamey. It has a shitload of iron. In my experience the taste changes a lot depending on the cut, more than beef, but to be honest, the vast majority of the time I eat horse meat, it's in the form of raw, ground meat.

Nope, it's much closer to beef than game or sheep, it's rich in iron and has a somewhat sweet flavour, more delicate than beef while actually being more tasty, if that makes any sense.
