Stouts are ales. The term ale has nothing to do with flavor, color, hoppiness, etc. It's all based on how it's fermented. All ales are top fermenting somewhere around 70 degrees F(IPAs, Stouts, Porters, Amber Ales, ESBs, Pale Ales, most Belgians, Hefeweizens, Kolschs, and about a billion other things). Lagers are the other major variety, and those include Pilsners, Bocks, Marzens, etc. They are bottom fermenting and typically ferment in the 38-45 degree F range.Mr. Eff said:Depends what you like in beer. Ale or stout? Do you like it hoppy?
Becks, Holsten, Carlsberg, and Innis and Gunn are my favourite beers. They're imports so you'll pay a little more, but they are delicious.
Just remember...

OP: I'd suggest learning to brew your own beer. I've been doing it for years now and could point you in a lot of the right directions if you'd like. It's tons of fun, it tastes better than most things you can buy on any shelf anywhere in the world, it's incredibly simple, you can start doing it with a friend or two, it usually cheaper than buying your own, and it's totally rewarding. Oh, and it'll keep you all boned up on your math, cooking, and organic chemistry skills (it really doesn't have to be that complex unless you want it to be...). There are usually homebrew shops in every semi-large town. If there isn't one near you, there are plenty that are online.
It's amazing. And easy. And cheap. There's no reason not to do it. Seriously, if you can make tea and can be mildly patient, brewing is for you. That goes for EVERYONE.
