It depends on the home imho and the buyer - some buyers would rather see personal pictures of family and happy times - it makes them feel like the house is a "home" - they like the fact a xmas tree is up etc etc
emotions play a huge roll sometimes in a buyers purchase - too much sometimes.
yes staging to a certain extent can work well - getting a home in good condition and showing it that way is staging - some people do need that extra help, Ill give you that.
