I go back and forth on this one. On one hand, it does not really add anything and for a long time I did not really use it. There isn't much point without an appearance system (or a more crucial one). ...
Yes, I love clutter items, but I rarely use moo. When I download a house I usually prefer it with out too much moo clutter. I do love to use different pieces on dressers, counters and tables, and as I play with a large rotation, it helps the houses look different and gives more realism. I say bring on more clutter in packs, but builders, please don’t over use it for your uploads. I like to be able to change a house around without having to go into moo.
