I think I did understand your question and I tried to give you an answer. I gave you a link that compares all these distributions, I'm not going to summarise all the information available there.
Is your project assignment to report on any one distribution or to report which is "the best"? If the latter, I repeat from my previous mail: "There is no best distribution", if the former, just pick one and don't worry about it any more. You can only solve your problem yourself by reading a little (a little, not a lot!) on each distribution and making your own mind up.
You also said you wanted help to decide what to use in your future (future career, I presume). Well, many people do have a favourite, that's true. If you want to hear about their reasons, just search this forum and read the hundreds of posts on the subject.
Also, if you have some time, access to a good network connection, and some diskspace, you can download two or three and try them yourself.
Good luck with that,
