Thanks, new releases now come out on the 15th for Manjaro, give or take a day. I am not sure of the ram usage compared to Manjaro Gnome or Xfce since I havent used either in quite some time. The good thing is that all the spins have a conky with ram usage so you know what you are using with a quick glance.
Cinnamon has always been one of my favs. I ran Mint for a few years in the past. But now days its LXQt on Manjaro because I have older hardware.
