It depends on the blend! The dust you get in some teabags is probably not the highest quality but not all loose leaf tea is great either. Some brands put the same high quality tea blends in their teabags too (an eg is Bird and Blend tea in UK), and the teabags aren’t made of plastic which can release small micro particles into boiled water. But then again, here in UK we all have our favourites and I’m not a snob, a good cup of tea is usually about how much limescale is in your kettle, the temperature of the water, and how long you leave the bag in the cup! I like both loose leaf and tea bag blends (in the UK we have so many great brands), depending on mood and what I’d like to drink.
