How does alcohol addiction compare to other drugs?

I would like to know how alcohol addiction compares to other drugs? I don't drink or do drugs, but I am writing this report and need to know as much as I can.
First of all, do you guys think alcohol is addicting (I wouldn't know because I never tried and never will)?
Second, how addicting is it compared to drugs like cocaine, meth, heroin, amephetamines, ecstacy, and marijuana?
Please rate in order if you have to.
Thanks.
