Red Stripe is a lager. Wouldn't exactly call it thick. It's an extremely light, American-style lager (yellow). Opinions aside it can't even be compared to Guinness because Guinness is a stout. The lager is called Harp. I consider Guinness to be the nectar of the gods.
Regular Pete's is a pretty good ale, a little on the sweet side for me. Strawberry Blonde is a fruit beer. Some people like them but personally I can't stand them.
