'Scuse me? Er, thanks for lumping us all together. Racist is such a sweet and generous term. And horrible and silly aren't too much better.
I know, I know, it's a shocker, but Judaism is no more a monolith of one person, one belief, one politics, one notion than any other group of more than three people is.
Anyway, that's a tangent. To answer your question, at least vis a vis Judaism. CoastalRat and Setanta have laid a foundation. Here's some more info.
Judaism is based on the Torah but we also have a number of written and oral laws. The written laws are in the Talmud and the unwritten ones, now in written form (confused yet?) are in what's called the Mishna. All of this stuff started off in Aramaic and then Hebrew but are now translated into quite a few languages including, of course, English. The Torah (commonly also called "the five books of Moses") covers creation, exodus (e. g. the movie, The Ten Commandments) plus a number of laws, including the basis of kosher law, plus a lot of odd stuff that most people these days find weird and antiquated, such as stuff about not planting two different types of crops together. Talmud and Mishna offer commentary on these and a lot of scenarios, kind of the specifics if you will. The Torah says to remember the Sabbath day and keep it holy, whereas the Talmud and the Mishna give more practical stuff about how to do it and what to do. Plus there are a bunch of prayers, in Hebrew but translated into slews of other languages. Depending upon how strictly religious you are, you pray in Hebrew or in the vernacular or in a bit of both.
One thing, though. Go into any synagogue --
any in the world -- and we're all on the same page. We start over every year, at the beginning of our year, which starts in about September to early October or so, a holiday called Rosh Hashanah. We start with creation and go along until, hmm, I can't recall. I think it all ends with Moses's death at Mount Nebo but I'm not certain. In any event, a Jew traveling to another part of the world can go into a synagogue and have a connection, even if it's a different sect. My father experienced this very thing in 1968. He was in Garmisch-Partenkirchen on business and it happened to be Passover. he asked for directions to a synagogue (there was one in a neighboring town) and could more or less follow along with the service, even with his old High School German. At the end of the service, a family approached him and asked him if he was an American and if he wanted a home-cooked meal the following night. He said sure, but it was also the Sabbath and it would not have been polite to write down the man's name and address (some stricter Jews -- we aren't -- don't write on the Sabbath). So the man told my Dad, oh, just ask for the only Jewish family in Garmisch-Partenkirchen. And so we made friends with this family. If Garmisch-Partenkirchen is a familiar place, it perhaps should be -- it's where Hitler had the winter Olympic games held in 1936.
Back to Judaism. There are, hmm, about a half a dozen sects. In order, more or less, of strictest to least strict, they are Orthodox, Hasidic (pretty much just an ultra-traditional form of Orthodoxy. Not everyone who is Orthodox is a Hasid, but all Hasidim are Orthodox), Conservative (that's me), Reconstructionist and Reform. I see on Wikipedia there's also one called Humanistic which I haven't heard of 'til now and haven't met anyone who is. See:
http://en.wikipedia.org/wiki/Judaism One thing about the sects, which is very different from Christianity and I believe also Islam, is that there is generally a great deal of play among the sects. A person can start off in one sect, move into another readily and then into a third or a fourth in life. I was raised in a Conservative household where we attended synagogue more often than the bare minimum (for a few years there, we went every single week), we kept kosher and celebrated all of the holidays. My brother and I both attended Hebrew School; he had a Bar Mitzvah, I did not have a Bat Mitzvah. But these days, I am much more like Reform. My husband is a Reform Jew and we aren't as observant. My brother, on the other hand, is more like Conservative, still, and even has some Orthodox tendencies at times. He is also married to a Jew and they are raising their son in our faith.
There's a lot more, of course, and it's not an Internet post you want; it's a class in comparative religions, assuming the reason for the question was an actual attempt at understanding, rather than an attempt to get people to do battle with one another. Is one faith better than another? I have no idea. I don't even know if one sect is better than another. I suppose the answer to the question of what is better is, like CoastalRat said, answered by understanding what is better for ourselves. What offers comfort, morality, love, spirituality? What feels right? What makes sense? What fits? We are all, ultimately, born to eventually die. It's how we fill up the space in between that means anything. If you choose to fill it with religion, then fine. If not, then fine, too. If with the same religion as mine, fine. If not, then fine, too.
