Well, since you asked...
You can't send links easily in hotmail. So yeah, hotmail bad. Anything that will send links good. I also know that the spam filter on most e-mail services (non-business) pretty well suck. Gmail has a spam filter that is excellent. Rarely does one get through. One click and they're all gone plus I get a Spam recipe, i.e salads, casseroles, etc. Aol's spam filter is so-so.
I wouldn't use anything related to MicroSoft for e-mail since that is the way most viruses get in. MS has too many weaknesses in their system.
Now, aren't you sorry you asked?
