Gmail has an excellent filter (and they nicely provide you with free "cooking with spam" recipes when you periodically purge the crap out of the spam folder). Yahoo's ain't bad. Hotmail's is not that great. The one one my home e-mail account (with Verizon) is damn near useless (the "filter" that Verizon provides with the service). I also have the spam filtering feature of Thunderbird enabled, which has proven completely worthless.

I'm not sure what we're using at work but it's EXTREMELY effective. In over two years there I think I've gotten one spam message and I've never had a legitimate e-mail blocked. I'm sure it's some kind of expensive hardware-based filter though - I'll check with I.T. to see if they'll tell me what it is.

For personal use, I'd say stick with the gmail account. Great interface, easy to use, good spam filter and able to be checked anywhere. Can't beat that.
