The autorefresher is more effective in refreshing, I dont think that is an oppinion matter, just a fact. I like to use the autorefresher when im hosting "unknown" maps with more than 6 players. There are a lot of weird named maps and people normally dont join those games, and I like to try out new maps. With the autorefresher I can get any game full, and the best part is you can just leave it there and do something else meanwhile (alt+tab).
