I use both SU and Armarize as well. SU is better for sync and updating mods and we use it on the Community Arma server. It makes it much easier for players to get the right mods/versions - find the server in SU browser, create new present and install. Armarize is great if you just want to fire up Arma with some mods loaded - program is faster to start, doesn't update every 30 minutes, uses far less RAM, etc. Just make sure you use SU to download and update mods. If you let Armarize do this it will screw up SU. http://www.veterans-gaming.com/vg-plugins/forum/forum_viewtopic.php?24065
