Keep in mind some of the garbage the carriers auto-install has caused some of the problems, and I believe HTC Home, itself, has been known to be one of the culprits.

All I can say is since using the 6.1 ROMs this hasn't been as much of a problem for me. When I close applications, most of the time their RAM clears up almost fully, and running Oxios once or twice a day, depending on what I've been using, is enough.
