does anyone have an opinion on using phplist vs mailman?

i want to have 3-4 lists for website visitors to sign up. i anticipate each list to be 300-400 users with newsletters going out 2-4 times per month (20-30K per newsletter).

which program has worked better for people?

which is easier for the end user to manage?

which is easier for you to manage?

blackburnrovers, here are some weblinks that introduce people's reflections over your question. Not much, but still something...:
