I usually just put 4 dryer balls in, sometimes the wool dryer balls since they make less noise. Usually do that when drying sheets since they have a tendency to ball up. Any dryer can have a tendency to ball up sheets at times, even the venerable Maytag HOH dryers. Though, the Maytag HOHs are good pillow and bedding dryers if you don’t like having to rearrange items every 30 minutes or so.
In my almost 10 years of doing my own laundry, no dryer is perfect, there’s anyways going to be idiosyncrasies with drying performance and characteristics, the design of the machine and components, options and features, etc.
