Tho i used to play addicting games way more, i like armor games more now. Addicting games holds onto their games for their Friday updates, and more often then not you can find it here first.
There really is no point in asking this question. Anybody that is posting here is going to be active on ArmorGames, rather than active on AddictingGames. This means that anybody posting here will prefer ArmorGames to AddictingGames. Also, these questions have been posted countless times before. It's getting old :/
