I find horses much more useful than horses because I've been killed atleast 10 times trying with a camel, but still haven't entirely given up on the camels.
But I suggest that Horses are more effcient in trades runs if you are a low level, keep swtching pack animals if you want. Also try out routes other players go through, if you find them easy use them a bit more than the normal routes picked by traders.
GOOD LUCK!!!!!!!
