I've kept pigs myself and we kept some sheep when i was younger - but too young to be very involved with their care.
IMHO pigs are better

Great fun to keep, VERY entertaining and lots of meat at the end
My feeling with sheep is that they're a bit more involved - plus you've got the worry of fly strike, the thought of all those maggots - yuck
But I could just be totally biased towards piggies

I'm sure the sheep experts may disagree - good luck whatever you decide
